Survival, Cox Regression, Kaplan Meier, Weibull Distribution, Accelerated Failure Time.
Rate is the integral function of all hazard rates over time. Hence, it is the expected number of failures over time interval [0,t] Cumulative hazard. Knowing what the hazard rate is we can start looking for median survival time which equals finding t such that S(t) = 0.5. This is the timepoint at
