I have a standard event history data set, which I used to fit a Cox proportional hazards model in Stata and R. The time variable is measured in days. There are no time-varying covariates on the RHS of the equation.
I have recovered the usual output (coefficients, hazard ratios, SEs, etc.) as well as the predicted baseline survival for each observation. What I need to do now is estimate the predicted number of events in the next 30 days. Any ideas on how to do this?
Thanks very much!
