Nick gave some code, and I too was busy along his line, with a slightly
different twist:
*---------------- begin example -------------------------
sysuse auto, clear
preserve
collapse (mean) mean=mpg (sd) sd=mpg (count) N=mpg ///
if !missing(rep78,foreign), by(foreign rep78)
gen se = sd/sqrt(N)
gen df = N-1
gen lb = mean - invttail(df,0.025)*se
gen ub = mean + invttail(df,0.025)*se
drop sd N df
reshape wide mean se lb ub, i(rep78) j(foreign)
mkmat mean0-ub1, matrix(table) rownames(rep78)
matrix colnames table = domestic:mean domestic:se domestic:lb ///
domestic:ub foreign:mean foreign:se ///
foreign:lb foreign:ub
matlist table, format(%9.2f) rowtitle("repair record") tw(13)
restore
*------------------- end example -----------------------------
(For more on how to use examples I sent to the Statalist, see
