Summary statistics loop stata

Instead, we can use the loops option available in Stata, and use the foreach command as follows - Notice that new variables have been created in your dataset

- Suppose we want to create a number of interaction variables by multiplying the polity variable with a number of selected variables (pcgdp, eduexp, govtexp)

To process, manipulate, and analyze data in Stata, we sometimes need to do repetitive tasks

Examples include recoding a set of variables in the same manner, creating or renaming a series of variables, or repetitively recording values of a number of variables

Using loops allows us to run the same codes once for repetitive work without typing them multiple times

- Using loops will keep your do-file concise

This guide discusses the two most common loop techniques available in Stata

We use foreach command for looping over variables or items
