It can only be added to the “Data Editor” (Edit) window.

However new variables cannot be added in this window. A new tab will open to define the value 1 for Male and 2 for females. Variable Manager window in STATAĬlick on “Add Value” to add codes to each sub-category of the variable.įor example: to add information about gender, click “Add Value”. In the case of categorical variables define values by clicking on “Manage”. Variable manager tab in STATA main windowĪ new window will open, Variable list in STATAįor each variable, the properties are defined on the right-hand side: Stata won't permit it, but even if it were allowed, it's pointless since Stata will preserve the variables specified in the -by()- option. On the main Stata window, click on “ variable manager” to manage variables. You can't have (first) countyID and also have countyID in the -by()- option. destring to convert string to numeric and vice a versa.Where make1 is the new variable in the numeric form. To generate a new var, use the command: destring make, gen(make1) In order to replace “make”, we will use the command: destring make, replace Strings can be converted into numeric in two ways. This command is used to convert string variables into numeric variables and vice versa. Since a string cannot be used for analysis, it should be converted to numeric.Ĭheck the data set in “Variable Window” (See below), wherein the Name, Label, Type and Format of the variable are defined.įor example: in this case since the var “make” is registered as str18 and in order to compute it as numeric, it has to be converted into a numeric. However, sometimes the variables which have numerical value is taken as string variable. So for example if in 1 1 1 0 there are three serial. Once the data is entered into STATA, it automatically defines the storage type of the data. Maximum number of variables is set to 32767 see help setmaxvar.

Similarly, “byte” size of numeric value would waste storage if it is saved as “double”. Only when all arguments supplied are missing does it show its own limited. This has a property which at first sight may seem surprising, but needs to be grasped. Note that since STATA stores information in the memory, the storage space should be used judiciously.įor example, the string female with a length of 6 would waste memory if stored as str20. The maximum of two values (the larger) in Stata is given directly by max(). The default value is xed for both Stata/IC and Small Stata. With Stata/MP and Stata/SE, this default value may be increased by using set maxvar. The default value of maxvar is 5,000 for Stata/MP and Stata/SE, 2,047 for Stata/IC, and 99 for Small Stata. Here str5 indicates its length.įor example, the male would be str4 (since the word ‘male’ has 4 characters) and females would be str6 (since the word ‘female’ has 6 characters). The maximum number of variables in your dataset is limited to maxvar. In case of strings, they are stored at str#, i.e.
