Hi! I am having a few problems with coxph function, I had the same problem with the use of survfit. Here it is: when calling 'M22<-coxphw(Surv(V1,V2,V4)~V5, data=XTDV, id=XTDV$V3, * prentice*= ~V5, robust=TRUE, censcorr=TRUE)' knowning that my data is: > XTDV[1:10,1:3] V1 V2 V3 V4 V5 1 0 36.39706 36 1 343.2224 2 0 36.39706 943 0 161.5931 3 0 36.39706 45 0 790.3714 I get this message: "...
