p. 37 of the Stata 8 svy manual gives returned values and some formulas. e(df_m) and e(df_r) don't quite correspond to the d.f. reported by the F stat but I suspect there is some trivial formula that shows the relationship. I know that, in writing my own program, I had to make sure e(df_r) was available when svy was used, otherwise I got z's instead of t's reported.

I think the -e(df_r)- of Page 37 of -[SVY]- probably applies to the case of scalar degrees of freedom, but not to the case of vector degrees of freedom.
