Cox’s semiparametric model is widely used in the analysis of survival data to explain the effect of explanatory variables on hazard rates. This paper shares the lessons we have learned from programming survival analysis with SAS for multiple sponsor clients. This article shows how to create a "sliced survival plot" for proportional-hazards models that are created by using PROC PHREG in SAS.

The PHREG procedure performs regression analysis of survival data based on the Cox proportional hazards model. This option has no effect unless the RISKLIMITS option is specified. The first example carries out a classical Cox regression analysis and the second example performs a Bayesian analysis of the Cox model. 3 was used to import the data as a comma separated value (. Parameters for Bayesian analysis were selected using the SELECTION option in the MODEL statement of the PHREG procedure with all potential predictors and no interactions. Residuals and other relevant statistics can be output also. com 12. The estimate is interpreted as the percent change in the hazards of the two population groups given an increase of one unit in a given explanatory variable and conditional on fixed values of all other explanatory variables. com SAS/STAT (R) 9. 2 User's Guide, Second Edition Tell us. It is also important to calculate the effects of variables on survival. 12.
