Wencke,

You can use -egen- to generate variables with the mean and standard deviation.

. sysuse auto
. bysort rep78 foreign: egen mpgmean = mean(mpg)
. bysort rep78 foreign: egen mpgsd = sd(mpg)

The mean and standard deviation can also be calculated with
-summarize-. Enter -return list- to see which results you can access
with other commands.

. sum mpg
. return list
. gen mpgmean = r(mean)
. gen mpgsd = r(sd)
