flexsurvspline with offset
...it1,type="survival",t=5)
y5_Flex <- y5_Flex_1[[1]]$est
y5_Flex
# Shrinkage factor
vanH <- 0.9589255
heuristic_lp_flex = vanH*predf??????
# Now calculate the shrunken model baseline survival prob at 5 years by fixing the shrunken lp as an offset and predicting the baseline survival
fit1_shrunk <- flexsurvspline(Surv(rfstime,rfs)~offset(heuristic_lp_flex),k=2,data=rotterdam)
The error message is
Error in model.matrix.default(forms[[i]], m) :
model frame and formula mismatch in model.matrix()
Any suggestions gratefully received!!!
Kind regards,
