data.princeton.edu7.1. THE HAZARD AND SURVIVAL FUNCTIONS 3 If we now integrate from 0 to tand introduce the boundary condition S(0) = 1 (since the event is sure not to have occurred by duration 0), we can solve

data.princeton.eduGiven the hazard, we can always integrate to obtain the cumulative hazard and then exponentiate to obtain the survival function using Equation 7.4. An example will help x ideas. Example: The simplest possible survival distribution is obtained by assuming a constant risk over time, so the hazard is (t) = for all t. The corresponding survival ...
