comparing the parametric survival regression models

[Sean Bilic]

What is the command for comparing the parametric survival regression models? For example, I estimate the model by both exponential and Weibull distributions. But, I also would like to compare (estimate) which distribution to use is better.

Thank you!

Sean:
-estat ic- is a possible option.
In addition, if time does not reach statistical significance in Weibull regression, other things being equal you could switch to exponential regression.

Hi,
Can someone help me with the suitable code for fitting a Weibull Proportional Hazard model to survival data?
