In RobinCar2: ROBust INference for Covariate Adjustment in Randomized Clinical Trials

Log-Rank Test via Score Function

Description

This function performs a log-rank test using the score function.

Usage

h_lr_test_via_score(score_fun, ...)

Arguments

score_fun	(function) The log-rank score function to be used for testing.
...	Additional arguments passed to score_fun.

Details

This activates the ties factor correction in the score function by passing use_ties_factor = TRUE to the score_fun.

Value

A list containing:

• u_l: The log-rank score statistic.

• sigma_l2: The variance of the log-rank statistic.

• tau_l: The log-rank test statistic.

• pval: The two-sided p-value of the log-rank test.
