Fabian, change egen meanwreturn_`l'=wtmean(trt1m) if SIZEBM==`l',weight(size) by(datemt) to read egen meanwreturn_`l'=wtmean(trt1m) if SIZEBM=="`l'",weight(size) by(datemt) Best Daniel -- Dear Statalist I have problems with the following commands: levelsof SIZEBM,local(levels) `"BH"' `"BL"' `"BM"' `"SH"' `"SL"' `"SM"' foreach l of local levels { egen meanwreturn_`l'=wtmean(trt1m) if SIZEBM==`l',weight(size) by(datemt) } BH not found r(111); wtmean is from SSC (David Kantor) to generate weighted mean. SIZEBM is a string variable. The aim is to calculate the size-weighted return for the different portfolios SIZEBM.
