For further information visit UNISTAT User's Guide section 9. If the predictor satisfy the proportional hazard assumption then the graph of the survival function versus the survival time should results in a graph with parallel curves, similarly the graph of the log(-log(survival)) versus log of survival time graph should result in. With trend lines, you can answer such questions as whether profit is predicted by sales, or whether average delays at an airport are significantly correlated with the month of the year. 00 Days to Event 0 200 400 600 800 1000 STRATA: treatmnt=1 Censored treatmnt=1 treatmnt=2 Censored treatmnt=2 Figure 1. , formerly Ill.
