In statistics and regression analysis, proportional hazards models are "statistical models used in survival analysis that assert that the effect of the study factors on the hazard rate in the study population is multiplicative and does not change over time."[1] Proportional hazards models assume that the relative risk remains constant over time.[2] The Cox proportional hazard model is an example of a proportional hazards model.
