st: some questions regarding stcox

Dear list,
1) what do the dots mean which I get instead of standard errors in
stcox? I get a coefficient but everything else is a "."
2) how do I compare the fit of 2 models?
3) can I use lagged variables when my analysis time is the real time or
do I need to correct for anything when doing so?
4) how can I instrument one of the independent variables?
Thank you very much.
Moqi
