I have a number of variables which are standard scores or scaled scores (language and congnitive test standardised scores) that I would like to convert to z-scores. I can do this manually by simply looking them up in a psychometric conversion table, however there are a lot of scores so I would like to do it in Stata. The command -egen(varname2) std(varname) - will not give the right answer, because it will create a new variable based on my data. I just want to transfer the standard scores onto the z-score scale, not actually create z-scores based on my dataset. Can I do this in Stata?
