st: correct for selection bias in survival analysis

[Marguerite Duponchel <Marguerite.Duponchel@malix.univ-paris1.fr>]

Hi,

I am running a loglog survival analysis as such:

streg duration_event vars, dist(loglog) cluster(y)

I need to correct for a selection bias in the sample using a probit on the
probability of the event happening.

probit event varsbis

Does anyone know an easier way to correct for a potential selection bias that
calculating the IMR from the probit and introducing it in the survival analysis
as an explanatory variable?


Thanks
