Dear Stata Members, I have to generate interaction variables between a country dummy and a time variable! I have a dataset with 50 countries. So using the tabulate command I get 50 dummy variables (country1, country2,....country 50). Now I want to multiply all these variables for a time variable! In this case I will generate 50 new variables! To do that, I can multiply each country dummy for the time variable. gen cy1=country1*year gen cy2=country2*years .... gen cy50=country50*years I was wondering if there exist any command to make this in a faster way!
