Dear R-users, I am trying to modify the mfp() function in the mfp package to model Weibull survival using fractional polynomials approach. However, I keep getting into trouble when mfp.fit and other "hidden" functions can't be found. I did find some of them in Splus but it's getting nowhere. I wonder if any of you can give me some tips on how to modify it or any experience modelling other survival models besides Coxph. Thank you very much! Regards Kelvin Lam, MSc.
