for -estat phtest- are apparently displaced from where they belong,
namely, the Methods and Formulas section for -stcox-.
However, the question remains, whether I should expect -estat phtest-
to work after -stcox, shared()-.

The Methods and Formulas documentation for for -estat phtest- describes in

seem to
actually work:
. stcox myvar, schoenfeld(var1) shared(frailvar)
. estat phtest
invalid subcommand phtest
r(321);
However, it works fine for the same model if frailty is not specified.
I found this identical problem posted a few months ago, but no responses.
Any ideas?
cheers,
Jeph
