Given any dataset of all numeric variables, I want to generate a new
variable called myMean, which is the arithmetic mean (the average)
across all the variables. The program below solves this problem. But
surely there is a one-line command that will perform this task in
Stata?
yes: -egen myMean = rowmean(var1 var2 foo bar etc)-
Hope this helps,
