respect to the things over which the loop runs. And these things are numbers. I do not see how I can name differently.

Only decimal points are problematic. Integer digits are allowed in variable names after the first character. The remedy is to use evocative names rather than numbers nevertheless. Only you can decide which names are best for your purpose. Why aren't you using -predict-? Nick n.j.cox@durham.ac.uk Thomas after a regression I would like to generate predictions for different values of the original variables. The first loop generate various scaled mean values. The second and third loop then generate the predictions c* for the various scaled means. The problem is how to name c*. Now the names include numbers which Stata does not accept (error: invalid name). Any ideas how I can get around this? ________________ foreach var of varlist yU yD{ sum `var' if e(sample) local m`var' = `r(mean)' local m25`var' = 0.25*`r(mean)' local m50`var' = 0.5*`r(mean)' local m75`var' = 0.75*`r(mean)' local m2`var' = 2*`r(mean)' local m3`var' = 3*`r(mean)' local m4`var' = 4*`r(mean)' } foreach i in `myU' `m25yU' `m50yU'{ foreach p in `myD' `m25yD' `m50yD'{ gen c`i'_`p' = _b[_cons]+_b[yU]*(`i')+_b[yU2]*((`i')^2/2) /// +_b[yD]*(`p')+_b[yD2]*((`p')^2/2) if e(sample) } } * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
