Survival Analysis Using SAS: A Practical Guide, Second Edition 2nd Edition PDF Survival Analysis using SAS (1992). SAS Code Debugging. PDF Tied survival times; estimation of survival probabilities 1.1 Kaplan-Meier, life table, and log-rank test using PROC LIFETEST The LIFETEST procedure can compute nonparametric estimates of the survivor function (us-ing either the actuarial or Kaplan-Meier method) and test the equality of survival . My general aim is to understand critical factors that affects customer defection over 36 months at individual level. The typical goal in survival analysis is to characterize the distribution of the survival time for a given population, to compare the survival distributions among different groups, or to study the relationship between the survival time and some concomitant variables.

For a more in depth discussion of the models please refer to section 9.2 of Applied Survival Analysis by Hosmer and Lemeshow. Chapter 5. Nevertheless, the tools of survival analysis are appropriate for analyzing data of this sort. Numerous examples of SAS code and output make this an eminently practical resource, ensuring that even the uninitiated becomes a sophisticated user of survival analysis. Easy to read and comprehensive, Survival Analysis Using SAS: A Practical Guide, Second Edition, by Paul D. Allison, is an accessible, data-based introduction to methods of survival analysis. .

Data Sets (Under Survival Analysis Techniques for Censored and Truncated Data) SAS Macros (Under Statistical Software by Faculty and Collaborators) Errors (pdf file) SAS. Step 1: Run the LIFETEST procedure and save the survival plot data to a data set using the ODS OUTPUT statement: Step 2: Now we define a GTL template called survival that uses a LAYOUT LATTICE with two rows and one column. The purpose of survival analysis is to model the underlying distribution of the failure time variable and to assess the dependence of the failure time variable on the independent variables. Goals of a Survival Analysis • Summarize the distribution of survival times -Tool: Kaplan-Meier curves • Compare the survival between groups, e.g., two treatments in clinical trial -Tool: Logrank test • Understand predictors of survival -Tool: Cox regression model/parametric models
