Lecture 17 Cox proportional hazards models BIOST 515 March 4, 2004 BIOST 515, Lecture 17 Review The proportional hazards regression model is given by h(t|X) = h(t) exp(X1β1 + + Xpβp). The predictors, X1, . . . , Xp are assumed to act additively on log h(t|x). log h(...
The model is based on the assumption that the baseline hazard function depends on time,t, but the predictor variables do not. This assumption is also called the proportional hazards assumption, which states that the hazard ratio does not change over time for any individual. ...

Cox proportional hazards regression models along with partial population attributable risks (PARs) and their 95% confidence intervals (CIs) were calculated to assess the relative population-level impact of the use of hormonal contraceptives on HIV-1 seroconversion rates and on pregnancy rates. 计算Cox...
Cox proportional hazards models are used to model survival time using covariates. They are available in Excel using the XLSTAT statistical software.
