Create dummy variable

Dummy variables are often used in regression analysis. Such variables need to be numerical and take the values 0 and 1.

This example shows how to make the dummy variable male. First, all values are set to 0. The replace command then replaces the value 0 with 1 where the variable gender takes the value ‘1’.

import db/BEFOLKNING_KJOENN as gender

//Create a dummy variable that indicates males based on the variable gender
generate male = 0
replace male = 1 if gender == '1'

tabulate male
