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)
