Dear All,

I am working on discrete-time proportional hazard models with a
non-parametric baseline hazard function, using -cloglog- in
person-period formatted datasets.

I would like to additionally calculate population attributable
fractions (PAFs) in these models.
However, I have never worked with PAFs in survival analyses before and
therefore don't know
which functions to use and how to correctly interpret the results.

Previously, I calculated PAFs in STATA with the -punaf- package from
Roger Newson, e.g.
for logistic regressions.

Can I use -punaf- here as well, just after calculating the estimates
over -cloglog-?

Or is there another function/package for this situation?

Or would it be better to calculate population attributable hazard
fractions (PAHFs) as described in Samuelsen & Eide (2008)?


Thanks for any help or advice on the subject.

Regards,
Angelo
