I am not sure about the "sample" thing. Could you rephrase your question? HTH Martin _______________________

Hi Martin,Thank you very much for the reply. I am VERY NEW to Stata. I am usingversion 10. I assume that pr is the DV and we f rep tr tu are the IVs. Isthere something that should replace "sample" such as _mj? I need tocalculate the beta values for the -mim- run on 5 imputed data sets. Thankyou.Best, Frank On Apr 30, 2009, at 6:50 PM, Martin Weiss wrote: <>If you think it is appropriate to do so, you can recover betacoefficients manually yourself.

I tried using the below commands, but resultsreturned no values.
