Dear all, 

we are conducting a study, by means bootstrapping, to identify the best parametric survival model associated to a sample. We select the best model comparing the AICs of them in every resample. 

In stata, do you know if it is possible to calculate any pseudo R2 (or another statistic) to obtain a measure of goodness-of fit for parametric models? We can't use graphical methods because we are working with multiple resamples (bootsrap).

Thanks in advance.

Albert Navarro
