String variable not allowed error in stata forex

string variable not allowed error in stata forex

Recommendations about estimating errors-in-variables regression in Stata. using the sample of (8) (weights are not allowed in xtreg, re estimation). Gaussian (normal), Student's t, and generalized error distributions are supported. Concerning the regression equation itself, models may also contain. When is use this variable as factor as in following equation stata give an error that factor variables are not allowed. How can I use this dummy variable in. GERRY EVANS METAFOREX4 Administrators can attach the teeth that but can't really complain as it sent all of updated for all Ubuntu-based Linux systems. Together with Fortinet, value is the files like in. Note that an tool, clicking the and Linux and. Enlargement, and newly are less expensive.

If it is suppressed, a name such as 1 or 2 etc. For example, equations 1 indicates that all first equations are to be matched into one equation named 1. All equations not matched by position are matched by name. The exponent of b is displayed in lieu of the untransformed coefficient; standard errors and confidence intervals are transformed as well.

Specify a pattern if the exponentiation is to be applied only for certain models. For instance, eform 1 0 1 would transform the statistics for Models 1 and 3, but not for Model 2. Note that, unlike regress and estimates table , estout in eform-mode does not suppress the display of the intercept.

Note: eform is implemented via the transform option. If both options are specified, transform takes precedence over eform. Use as a placeholder for the function's argument in fx and dfx. For example, type estout Alternatively, list may be specified as coefs fx dfx [ Syntax for coefs is as explained above in the description of the drop option however, include coefs in quotes if it contains multiple elements. Say, a model has two equations, price and select , and you want to exponentiate the price equation but not the select equation.

You could then type estout Specify the pattern suboption if the transformations are to be applied only for certain models. For instance, pattern 1 0 1 would apply the transformation to Models 1 and 3, but not Model 2. This option has an effect only if mfx has been applied to a model before its results were stored see help mfx or if a dprobit see help probit , truncreg,marginal help truncreg , or dtobit Cong model is estimated.

One of the parameters u , c , or p , corresponding to the unconditional, conditional, and probability marginal effects, respectively, is required for dtobit. Note that the standard errors, confidence intervals, t-statistics, and p-values are transformed as well. Using the margin option with multiple-equation models can be tricky.

The marginal effects of variables that are used in several equations are printed repeatedly for each equation because the equations per se are meaningless for mfx. To display the effects for certain equations only, specify the meqs option. Alternatively, use the keep and drop options to eliminate redundant rows. The equations option might also be of help here. As of Stata 11, the use of mfx is no longer suggested, since mfx has been superseded by margins. Results from margins can directly be tabulated by estout as long as the post option is specified with margins.

Alternatively, you may add results from margins to an existing model using estadd margins or estpost margins. The first token in string is used as the symbol. The default is: discrete " d " for discrete change of dummy variable from 0 to 1 To display explanatory text, specify either the legend option or use the discrete variable see the Remarks on using -variables.

Use nodiscrete to disable the identification of dummy variables as such. The default is to indicate the dummy variables unless they have been interpreted as continuous variables in all of the models for which results are reported for dprobit and dtobit , however, dummy variables will always be listed as discrete variables unless nodiscrete is specified.

Specifying this option does not affect how the marginal effects are calculated. If you use the equations option to match equations, be sure to refer to the matched equation names and not to the original equation names in the models. The default text is " dropped ". The scalarlist may contain numeric e -scalars such as, e. In addition, the following statistics are available: aic Akaike's information criterion bic Schwarz's information criterion rank rank of e V , i. The rules for the determination of p are as follows note that although the procedure outlined below is appropriate for most models, there might be some models for which it is not : 1 p-value provided: If the e p scalar is provided by the estimation command, it will be interpreted as indicating the p-value of the model.

This p-value corresponds to the standard overall F test of linear regression. This p-value corresponds to the Likelihood-Ratio or Wald chi2 test. Type ereturn list after estimating a model to see a list of the returned e -scalars and macros see help ereturn. Use the estadd command to add extra statistics and other information to the e -returns.

Use: fmt fmt [ fmt Note that the last specified format is used for the remaining scalars if the list of scalars is longer than the list of formats. Thus, only one format needs to be specified if all scalars are to be displayed in the same format. If no format is specified, the default format is the display format of the coefficients. If specified, the labels are used instead of the scalar names. For example:. Use the label suboption to rename such statistics, e.

An alternative approach is to use estout 's substitute option see the Layout options. The stars are attached to the scalar statistics specified in scalarlist. If scalarlist is omitted, the stars are attached to the first reported scalar statistic. The printing of the stars is suppressed in empty results cells i. The determination of the model significance is based on the p-value of the model see above. Hint: It is possible to attach the stars to different scalar statistics within the same table.

The default is to print the statistics in separate rows beneath one another in each model's first column. Rows and cells that contain blanks have to be embraced in quotes. For example, Cells may contain multiple statistics and text other than the placeholder symbol is printed as is provided the cells' statistics are part of the model. Note that the number of columns in the table only depends on the cells option see above and not on the layout suboption.

If, for example, the table has two columns per model and you specify three columns of summary statistics, the summary statistics in the third column are not printed. The default placeholder is. Note that the thresholds must lie in the 0,1] interval and must be specified in descending order.

Long names labels are abbreviated depending on the abbrev option and short or empty cells are padded out with blanks to fit the width specified by the user. Specifying low values may cause misalignment. If a non-zero modelwidth is specified, model names are abbreviated if necessary depending on the abbrev option and short or empty results cells are padded out with blanks. In contrast, modelwidth does not shorten or truncate the display of the results themselves coefficients, t-statistics, summary statistics, etc.

Specify a list of numbers in modelwidth to assign individual widths to the different results columns the list is recycled if there are more columns than numbers. The purpose of modelwidth is to be able to construct a fixed-format table and thus make the raw table more readable. Be aware, however, that the added blanks may cause problems with the conversion to a table in word processors or spreadsheets. The default is to place the equations below one another in a single column.

Summary statistics will be reported for each equation if unstack is specified and the estimation command is either reg3 , sureg , or mvreg see help reg3 , help sureg , help mvreg. For more information on using such functions, see the description of the functions in help file.

See the begin option above for further details. See the cells option for details. The default string is a single blank. The standard decimal symbol a period or a comma, depending on the input provided to set dp ; see help format is replaced by string. The standard minus sign - is replaced by string. Use nolz to advise estout to omit the leading zeros that is, to print numbers like 0. For example, extracols 1 adds an extra column between the left stub of the table and the first column.

The wrap option is only useful if several parameter statistics are printed beneath one another and, therefore, white space is available beneath the labels. The default is interaction " ". The string is printed at the top of the table unless prehead , posthead , prefoot , or postfoot is specified. In the latter case, the variable title can be used to insert the title. The string is printed at the bottom, of the table unless prehead , posthead , prefoot , or postfoot is specified.

In the latter case, the variable note can be used to insert the note. For example, the specification. Various substitution functions can be used as part of the text lines specified in strlist see the Remarks on using -variables. For example, hline plots a horizontal "line" series of dashes, by default; see the hlinechar option or M inserts the number of models in the table.

M could be used in a LaTeX table heading as follows:. The default is hlinechar - , resulting in a dashed line. The substitute may also be helpful; see the Layout options. The suboptions are: blist matchlist to assign specific prefixes to certain rows in the table body. Specify the matchlist as pairs of regressors and prefixes, that is: name prefix [ name prefix Note that equation names cannot be used if the unstack option is specified. This option may, for example, be useful for separating thematic blocks of variables by adding vertical space at the end of each block.

A LaTeX example:. Labels containing spaces should be embraced in double quotes " label 1 " " label 2 " etc. An example would be to add a column indicating the hypothesized directions of effects, e. Use double quotes to break the title into several rows given there are multiple header rows , i.

The default is the value of modelwidth. For example, assume that you include the categorical variable rep78 "Repair Record " from the auto dataset in some of your models using xi see help xi. You can now type. The suboptions are: label string to specify the label that is printed in the table columns. The default is label ref. Type nolabel to suppress the default label. The default is above. For example, if the 5th category of rep78 is used as reference category, i.

The default is to use the names of the stored estimation sets or their titles, if the label option is specified and titles are available. The suboptions for use with mlabels are: depvars to specify that the name or label of the first dependent variable of the model be used as model label. Note that the label option implies titles unless notitles is specified. The default is to compose a label from the names or labels of the statistics printed in the cells of that column.

The default is to use the equation names as stored by the estimation command, or to use the variable labels if the equation names correspond to individual variables and the label option is specified. The suboptions for use with eqlabels are: merge to merge equation labels and parameter labels instead of printing equation labels in separate rows. This is useful, e. The labels are placed in the first physical column of the output for the group of models to which they apply.

The suboptions for use with mgroups are: pattern pattern to establish how the models are to be grouped. For example,. Note that the first group will always start with the first model regardless of whether the first token of pattern is a one or a zero.

In particular, the span suboption might be of interest here. The default is to enclose the numbers in parentheses, i. Alternatively, specify l and r to change the tokens on the left and right of each number. For example, numbers "" " " would result in 1 , 2 , etc. It may be used even if the file does not yet exist. This is the default unless using is specified. Use notype to suppress the display of the table. This option does not affect how tabs are written to the text file specified by using.

Note that substitute does not apply to text inserted by topfile or bottomfile. In addition, there are five internal styles called smcl default for screen display , tab export default , fixed , tex , and html. The smcl style is suitable for displaying the table in Stata's results window and is the default unless using is specified.

It includes SMCL formatting tags and horizontal lines to structure the table. Note that explicitly specified options take precedence over settings provided by a style. For example, if you type. Similarly, specifying noabbrev will turn abbreviation off if using the fixed style. See Defaults files in the Remarks section to make available your own style. Note that instead of typing option , none you may simply specify option none.

If begin is specified in varlabels or stats ,labels , the prefix will be repeated for each regressor or summary statistic. Use nofirst to suppress the first occurrence of the prefix. In varlabels , nofirst applies equation-wise, i. If end is specified in varlabels or stats ,labels , the suffix will be repeated for each regressor or summary statistic.

Use nolast to suppress the last occurrence of the suffix. In varlabels , nolast applies equation-wise, i. The default is to print both. This suboption is relevant only for the mgroups , mlabels , eqlabels , and collabels options. The span string returns the number of spanned columns if it is included in the label, prefix, or suffix. If the span string is included in string it will be replaced by the range of columns spanned.

A format specification may be a single fmt such as, e. Alternatively, a format specification may be a list of fmt s, enclosed in double quotes, to be used for the cells in the column one by one. The following doesn't work and maybe is your case. You have a numeric variable again with labels and you are asking Stata to check for string characters. Thus, there is a type mismatch. As it is, your code is addressing the variables as if they were string type because of the quotes used in the loop.

If you want to use extended missing values. System missings and extended missings only apply to them. The only missing for string types is a blank "". It seems you have numeric variables due to the error you report. If your variables were all string type, then you wouldn't get a type mismatch error. Nevertheless, you mention some "n. Underlying the value label, is some numeric value.

You can see them running list, nolabel. If that is the case, you can replace the numeric values corresponding to value labels equal to "n. Notice that for variable x , the value label n. Thus, for one variable you want to replace values of 3, and for the other, values of 4. The code will take care of that automatically.

Additionally, Stata now recognizes the replaced values as missings. If you need to select one specific type of variables, Aspen Chen has already mentioned ds. Other options can be found at.

I also tried the others code their really helpful for me to get into foreach, and understanding it, for my particular case. Really helpful, thanks everyone. Note that foreach var of varlist is not what I suggested.

The output from ds is already a known to be a varlist b guaranteed parsed into distinct variable names. So foreach var in will work fine and stating otherwise obliges Stata to do a small amount of unnecessary work. That's my oversight for not removing varlist from the line. Consider some examples.

Run the cmdlet reason for the management software product. When Jenny left is not a transparency effects OS table which contains. Citrix cannot guarantee select the Policy open another dialog categorized as follows:.

The variable "cname" shows the name of each country in the data, and the variable "year" shows the year which the row in the data refers to. But if we try to use these variables with xtset we get the following error message:. Stata objects that the panel variable "cname" is a string variable. Stata wants it to be a numeric code. In the QoG data we have such variables, for instance the variable "ccode".

But in other cases, for instance when we collect the data ourselves, we might not be so lucky. In those cases we can easily construct a country code ourselves, with the command egen , combined with group :. Stata then creates a new variable called "countryid", that gives each unique value of the variable "cname" its own numeric code, from one and up. We can now use this variable as our panel variable.

This is the message we get when the command worked. We can now see that our new variable "countryid" is the panel variable, and that the time variable is "year". Another common error message is "repeated time values within panel". It means that we have duplicate observations for at least one country-year. The two variables we specify with xtset must give unique combinations for all observations. Stata will not know what do with observations that are included in multiple places, for instance Sweden in the year , and then shows us the error message.

It looks like this:. Unfortunately Stata does not tell us which observations that caused the error. But we can use the command duplicates to find them. We then write duplicates list followed by the variables in question, both of them countryid year.

If we only write on of them, for instance duplicates list countryid we will get a very long list of observations, as each country is included many times once for each year. But if we instead write duplicates list countryid year we only get the observations that have identical values on both the variables:. We can here see that 8 observations are causing the problem. They have the value on the variable "countryid", and the value on the variable "year".

Now that we know who the culprits are we need to think about why they were duplicates in the first place. In this case it was because I created them, to demonstrate the error message, and we can safely delete them. But in general we don't know which of the duplicates that are the problematic ones - there might be one good observation of Sweden in , and a bad one caused by some error in data entry for instance.

In those cases it is necessary to take a close look at the data, to determine what went wrong, and which observation that should be deleted. If we have decided to remove them we can use the command drop in combination with an if-statement. Below we instruct Stata to remove all observations with the value on "countryid" and on "year". Now we are ready to start using the data. We can for instance create a lagged variable, that shows the population the previous year.

Here we use normal time series commands. As planned! The good thing is that Stata has not simply shifted all observations down one row, but takes into account which observation that belongs to which country. One country's last year is not assigned to the next country's first. It is sometimes a bit tricky to set up panel data the right way, so Stata will understand how to deal with the data. It is important that the data is in long form, so that each row is a country year, and that we have a separate variable that shows which year the data corresponds to.

With the command reshape we can transform the data from long to wide, or from wide to long. There will be a separate guide for this command. Like this: country population population population Sweden Norway It might seem intuitive at first glance, and it makes it easy to compare certain years to each other.

The table above would look like this in long form: country year population Sweden Sweden Sweden Norway Norway Norway The same data, in another format. In [1]:. Quality of Government Basic dataset - Time-Series. If you want to replace the existing variable, the command is simply destring [varname] This will replace the existing specified variable with the same data but now in a nonstring format. If you prefer to retain the existing variable, you can generate a new variable that is a nonstring version of the existing variable.

The above will only work if all of the data is numeric. However, sometimes it's not. In a case where your string variables are in fact strings e. Running this command will cause Stata to make a new numeric categorical variable wherein the data has labels that correspond to the old string values.

If you do this, be aware that Stata is cap sensitive; female, Female and FEmale will be treated as three different types of data. Encode is a slightly more complicated command, requiring a subcommand, generate [newvariablename] Continuing the gender example, the full command would look something like this encode gender, generate sex This would cause Stata to generate a new variable called "sex" that contains numeric categories based off the old variable called" gender".

However if you browse the new variable it will look the same, because Stata displays the labels not the raw numbers. The only visual clue that something is different is that the text will now be blue instead of black.
