Hi everyone,

I was wondering whether extension of the current spower function for Hmisc were existing?

My current focus is to calculate sample size based on the log-rank test with more than 2 groups (with/without trend)

Taking into account the loss of follow up and the accrual processes.

A SPSS library (ART) is existing but can't find anything in R

Any information is welcome !

Many thanks

Laurent
