1. Sandi implied that she was using the survey commands (by mentioning svyset). They do not support the beta option.

2. However, if Sandi only has pweights and not a complex design (with clustering or stratification), she can use "regular" -regress- with a pweight and specify the beta option as Martin suggested.

3. I assume there is a reason having to do with the survey method of variance estimation that explains why the svy commands do not produce betas and why programs like listcoef and betacoef don't work with them, but I don't know what it is.

Subject: st: standardized coefficient in survey weighted regression using spost9

I am running a weighted linear regression (using a sampling weight or "pweight") using svyset commands. Following a previous listserv discussion, I downloaded spost 9 and used the command listcoef so I could obtain standardized betas for this regression. (I have a reviewer specifically asking for this.) However while it works, I get the following warning:

"pweights not compatible with summarize; weights will be treated as aweights"

Can someone tell me how this might be affecting the standardized beta that I want to report?
