Описание: Stata Tutorials Topic 28: Extensions to generate (egen) | Summary Statistics and Data Management Using Stata

Hi, I am Bob. Welcome to the Stata course that helps you understand Stata commands for summary statistics and regression analysis. Today, we will explore the "egen" command. The "egen" command creates new variables from existing variables using functions. The "egen" command is more powerful than the "generate" command, making some complicated coding much easier. The "egen" command is used with functions.

Please download the BOB.dta dataset:
