Survival Analysis Using Cox Proportional Hazards Modeling For Single And Multiple Event Time Data Tyler Smith, MS; Besa Smith, MPH; and Margaret AK Ryan, MD, MPH. Department of Defense Center for Deployment Health Research, Naval Health Research Center, San Diego, CA. Abstract customers became more demanding of safer, more reliable products. As the use of Survival Analysis grew, researchers Survival Analysis techniques are often used in clinical and began to develop nonparametric and semiparametric epidemiologic research to model time until event data. approaches to fill in gaps left by parametric methods. Using SAS system's PROC PHREG, Cox regression can These methods became popular over other parametric be employed to model time until event while methods due to the relatively robust model and the ability simultaneously adjusting for influential covariates and of the researcher to be blind to the exact underlying accounting for problems such as attrition, delayed entry, distribution of Survival times.
