Dear Stata Users,
To this solution i have 2 questions:
1) What is the meaning of the transpose mark, in my opinion the syntax should also run without this mark.
2) if i like getting not alone the results of the total mean but also the differences between the mean of all items and grouped items i used the following ado file. My question is, is there a way to use the labels of the by-variable for the matrix list command at the bottom?
Thanks very much
Stefan
program define compmean
version 8.0
syntax varlist [if] [in], by(varname)
marksample touse
quietly levels `by' if `touse', local(K)
* total
di as text _newline(2) "{hline 104}"_newline "total means"_newline
tabstat `varlist' if `touse', stats(mean) format(%9.3f) save casewise
matrix total = r(StatTot)
di _newline "{hline 104}" _newline(2)
* groupwise
di _newline "{hline 104}" _newline "means of the groups" _newline
tabstat `varlist' if `touse', stats(mean) by(`by') format(%9.3f) save casewise nototal miss
di _newline "{hline 104}" _newline(2)
* matixes of the means of the groups and differencies of the means
foreach num of numlist 1/`K'{
matrix cl`num' = r(Stat`num')
matrix cl`num't = (cl`num' - total)*100
}
* display
di _newline(2) "{hline 104}" _newline "differences of the means" _newline
foreach num of numlist 1/`K' {
di _continue "Cluster `num' "
matrix list cl`num't, noheader format(%9.1f) noblank nonames
}
di "{hline 104}"
end
exit
