Log-Logistic ModelLoglogistic Regression Model, Fisk Survival Model
A survival model based on the log-logistic distribution, representing a hazard function that rises to a peak and then declines.
Log-Normal ModelLognormal Survival Model, Lognormal AFT
A survival model based on the log-normal distribution, capable of representing a hazard that rises then falls, similar in shape to log-logistic.
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.
