Abstract
In survival analysis, comparison of survival times between two groups of patients is often the goal. For this purpose, Mantel-Haenszel (or log-rank) test is usually used. This paper introduces a concrete example to illustrate similarities as well as differences among the statistical programs SAS, S-PLUS and STATISTICA, when performing Mantel-Haenszel test.
