Hi,

I"m currently working on two data analysis projects.
The first is a survival analysis using univariate and
multivariate Cox proportional hazards regression. How
do I check the goodness of fit of my final model? Are
there commands analogous to lfit and lroc for logistic
regression?

My second analysis is analysis a survey database
sample. I'm running svylogit, and svyregress commands
for dichotomous and linear predictors. How do I test
the fit of my final model? I'm not able to run
commands like svylroc or svylfit (comes up as
unrecognized commands)


Thanks,
Ashwin
