Fractional Polynomials in Competing Risks setting
...uggest how I can effectively combine these situations i.e. is there a way to apply the fractional polynomail transformation to the variable to assertain whether the transformation improves the model fit? I've tried the following code but it doesn't actually transform the variable: fitf=crr(nearmb$with.Withtime,censaeb,as.matrix(fp(nearmb$all.firstint)),failcode=2,cencode=0) Thank you for your help, Laura
