st: Obtain p-values for GEE models after bootstrap

Hello,
I'm trying to obtain bias-corrected p-values for GEE regression with
bootstrap estimation. I used to obtain p-values after bootstrap by
following steps outlined by Buis
(http://www.stata-journal.com/article.html?article=st0137), using the
commands:
local t = _b[var1]/_se[var1]
di 2*ttail(e(df_r),abs(`t´))
But this approach failed after GEE because stata does not save the
residual degree of freedom as e(df_r) for GEE regression. So is there
a way to obtain p-values after using bootstrap for a GEE regression in
STATA? Thank you very much.
Irene
