Bayesian Nonparametric Nonproportional Hazards Survival Modeling
Bayesian Nonparametric Nonproportional Hazards Survival Modeling
We develop a dependent Dirichlet process model for survival analysis data. A major feature of the proposed approach is that there is no necessity for resulting survival curve estimates to satisfy the ubiquitous proportional hazards assumption. An illustration based on a cancer clinical trial is given, where survival probabilities for …
