웹2016년 5월 12일 · Use the “basehaz” function to obtain an estimate of the baseline cumulative hazard function. Use this to compute the predicted survival curves for the control and experimental groups based on the proportional hazards model we fitted in Sect. 5.2 . 웹2024년 12월 22일 · 1 Answer. The proportional hazard model assumes hazard rates of the form: h ( t X) = h 0 ( t) ⋅ r i s k ( X) where usually r i s k ( X) = e x p ( X β). The xgboost predict method returns r i s k ( X) only. What we can do is use the survival::basehaz function to find h 0 ( t).
