Re: st: regression coefficient by group

["Roger B. Newson" <r.newson@imperial.ac.uk>]

And, if you want to recover confidence limits and P-values as well as 
just the regression coefficients, then you might use -parmby- instead of 
-statsby-. The -parmby- command is part of the -parmest- package, which 
you can download from SSC. It creates an output dataset (or resultsset) 
with 1 observation per parameter per by-group and data on parameter 
names, estimates, confidence limits, P-values and other parameter 
attributes.

Best wishes

Roger
