I wonder if there is a simple way of doing this? My data is very simple, a right censored outcome (T,delta) and the predictor is simply Z*t, i.e., the cox model is like h(t)=h0(t)exp(beta*Z*t)
That looks more like an accelerated time model than a Cox model. Is this homework for a course? Why is the form of the model specified if you haven't done any investigation?
