i am trying to fit a survival regression model (cox model or parametric model) in R by including the covariate effects as a function m(x) instead of just beta*x. is it possible to fit such a model? can someone recommend some reference? I searched but only found a package called addreg where the hazard is actually modeled additively. That is not what i want.
