WebMar 18, 2024 · The function survdiff in the R package survival implements the G-rho family of tests suggested by Flemming and Harrington (1981). Calling survdiff with rho=0 (the default) yields the logrank test. Calling survdiff with rho=1 yields the Peto-Peto test based on the Kaplan-Meier estimate of survival.

A significant test means there are some differences between the hazard/survival functions of the K samples. This should usually be followed up by more specific tests to locate where the differences lie.
