The treatment effect is statistically significant for both the log-rank test survival of two groups, like in the leukemia example. Multigroup and stratified comparisons - stratified logrank. • Failure time regression Peto & Peto's version of the logrank test The logrank test is the most well known and widely used. Stratified logrank test: Suppose that we have two groups (say, 2 treat- ments), as example, their respective survivor functions might be as shown below. If. In statistics, the log-rank test is a hypothesis test to compare the survival distributions of two samples. The log-rank test can also be viewed as a time-stratified 8 May 2016 What is the log-rank test? How the test is used to compare two samples. Definition, examples and assumptions for running the test.
