----begin included message -------- I'm trying to estimate a Cox proportional hazard model with time-varying covariates using coxph. The parameter estimates are fine but there is something wrong with the survival curves I get with survfit (results are not plausible).
-- end inclusion ---- This sounds wrong to me also. Could you give more information so that I can verify the issue? (See the posting guide). What version of R and of the survival package? Is is possible to send me a copy of the example that fails?
