I have written the ultimate guide on renaming variables in Stata. Sometimes, we need to rename the existing variables names. There may be multiple reasons to change the variable names. For example, the name of a variable is too long and when you do analysis in Stata, the name of variable appeared weirdly in the data table. Therefore, renaming of a variable is required for this.
There are numerous commands to change variables’ names. In this conclusive guide, I have listed all the commands and techniques to rename variables in Stata.
Data Description
I have used the built-in data set from Stata software. The data set have values of Automobile sector of 1978. To use the data set, use following code:
sysuse auto2.dta
To see what variables in the data are, we use the following command:
describe
Change variable Name in Stata:
In above picture, we can see that there are different variables. For example, mpg is a variable which means Mileage. If we want to change this variable name from mpg to mileage, use the following command:
rename mpg mileage
To see the updated variable names, use describe command again:
describe
We can see now that variable name mpg has been changed to mileage. In this way, we can rename variables in Stata.
