Hi,
I'm using crrstep package to do stepwise covariate selection for the Fine &
Gray competing risks regression model. However, I keep getting an error
(please see below). Please help!!
> PHstep <-
crrstep(years~1+var1+var2+var3+var4+var5,scope.min=~1,censorcmprsk,
data=crisk, direction=c("forward"), crr.object = FALSE, trace = TRUE, steps
= 100)
crrstep(formula = years ~ 1 + var1+var2+var3+var4+var5, scope.min = ~1,
etype = censorcmprsk, data = crisk, direction = c("forward"),
crr.object = FALSE, trace = TRUE, steps = 100)
*Error in crr(ftime, fstatus, cov1, variance = TRUE, ...) :
unused argument(s) (variance = TRUE)*
Thank you very much!
