Under -egen- you will find the -rowmean- function:

  egen mymean = rowmean(var1 var2 var3)

will do what you want.

I've always that -egen- was "underindexed"; you can't
find this functions even with -search rowmean-.

hope this helps,
Jeph

Dear Statalist Members,
I would like to know how to build mean variables in Stata.
To be more specific, suppose that I have three columns/variables
indicating sales in 3 different years for each observation, and I'd
like to build a fourth column which contains the mean of sales in the
three years for each observation.
Could you please indicate me the code? (I have already checked in the
manual but I could not find anything that helped me)
Thank you very much
A.R.
