psfmi_coxr does not work with stratified cox model

[AimSchina]

Hi all,
thank you for providing this amazing package! I have tried to used psfmi to run a stratified cox model, but as it seems this is not implemented. Interactions and splines are covered, yet is there any plan of including this feature in the future? Thank you!

Thanks for using the package and your kind words. I think that it is easy to adjust. I will try to fix this before the beginning of March, first in the development version.

That is great, thank you!

It is now possible to pool and select stratified Cox models by using the strata option in the formula. Have fun!
