The hazard ratio for these two cases, h i(t) h i0(t) = h 0(t)e i h 0(t)e i0 = e i e i0 is independent of time t. Consequently, the Cox model is a proportional-hazards model. Remarkably, even though the baseline hazard is unspeci ed, the Cox model can still be esti-mated by the method of partial likelihood, developed by Cox (1972) in the same

Cox Regression Model . This is the alternative to the standard regression when you have censored events (this is Survival Analysis).It is found that there are significant differences between the treatments in terms of survival time, and this difference can be summarized with a COX regression model, which raises a relationship for the risk between the alternative group, for example men with

Cox Proportional Hazard is a regression technique that incorporates the element of time-to-event into the computation of a hazard ratio. A censoring variable The proportional hazards assumption is so important to Cox regression that we often include it in the name (the Cox proportional hazards model). What it essentially means is that the ratio of the hazards for any two individuals is constant over time.
