Web1. Introduction. Survival analysis models factors that influence the time to an event. Ordinary least squares regression methods fall short because the time to event is typically not normally distributed, and the model cannot handle censoring, very common in survival data, without modification. Nonparametric methods provide simple and quick ... WebODS Statistical Graphics is an extension to ODS used to create analytical graphs. It was introduced as part of SAS/GRAPH in SAS 9.2, but was moved into the Base SAS product starting with version 9.3.
