In a case where your string variables are in fact strings eg female instead of 1 you have to tell Stata to encode varname the string data. Gen rep78In rep78 5 if missingrep78. This command generates a new variable named rep2 which takes on the value of 1 only for observations where rep78 is equal to 2.

You could type. Researchers may often need to create multiple indicator variables from a single often categorical variable. I would then create other dummies equal to 1 if.

Countries below 50 of urbanization0 above 501. I know that I can do this using something like the following but for all 25 dx variables. ELSE IFFINDroleceoi0 THEN DO.
