Hello,

I have a question concerning the output of a Cox regression, which I
want to access with outreg2. Below you find the results of the Cox
regression command as well as the ereturn list results. My question
is: Why doesn't the  e(r2_p) =  .0006402283288656 repor the  Prob >
chi2     =    0.0025?
How can I access the Prob > chi2?

Thank you for you help,

dirk
