I'm working on a survival model. And I would like to compare different models in how good they are at predicting a duration.
For example I would like to compare the following models:
streg i.gender i.industry, distribution(e) nohr
streg yrbirth i.industry, distribution(e) nohr
streg i.gender yrbirth i.industry, distribution(e) nohr

I read up that r-squared can be used only in linear regressions https://statisticsbyjim.com/regressi...ar-regression/

What is an alternative measure for non-linear regressions? And what command can I use to display it?
