Pairwise survdiff r

WebJul 1, 2014 · I've been working on putting together a survival analysis using Kaplan-Meier and the logrank test. I am doing the testing in R with survdiff(). Each plot has multiple groups/curves, and I've been testing for the difference between groups (where there are more than two) by doing individual pairwise tests, as has been suggested elsewhere. WebDescription. This function implements the G-rho family of Harrington and Fleming (1982), with weights on each death of S ( t) ρ , where S ( t) is the Kaplan-Meier estimate of survival. With rho = 0 this is the log-rank or Mantel-Haenszel test, and with rho = 1 it is equivalent to the Peto & Peto modification of the Gehan-Wilcoxon test.
