F
- Fleming-Harrington TestFleming-Harrington Weighted Test, G-Rho Test
- A hypothesis test comparing survival distributions between groups, generalising the log-rank test by allowing different weights for events at different follow-up times.
L
- Log-Rank TestMantel-Cox Test, Mantel-Haenszel Survival Test
- The log-rank test is a nonparametric hypothesis test that compares the event-time distributions of two or more groups by accumulating observed-minus-expected events across distinct event times while accounting for right censoring.
P
- Peto TestPeto Log-Rank Test, Peto Method
- A Peto–Peto weighted test for comparing time-to-event distributions, using observed-versus-expected events with weights based on pooled survival that emphasize earlier event times.
S
- Stratified Log-RankAdjusted Log-Rank, Stratum-Adjusted Test
- A variant of the log-rank test accounting for stratifying variables, comparing survival within each stratum before combining into an overall statistic.
W
- Wilcoxon TestWilcoxon Rank-Sum Test, Wilcoxon Signed-Rank Test
- A test comparing survival distributions that gives greater weight to earlier event times than later ones, unlike the standard log-rank test.
