For a one-sample test, the predictors must consist of a single offset(sp) term, where sp is a vector giving the survival probability of each subject. 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.

WebMar 26, 2024 · A log rank test is the most common way to compare survival curves between two groups.. This test uses the following hypotheses:.
