wlr_weight: Weight Function of Weighted Log-rank Test

In keaven/gsDesign2: Group Sequential Design with Non-Constant Effect

Weight Function of Weighted Log-rank Test

Description

• wlr_weight_fh is Fleming-Harriongton, FH(rho, gamma) weight function.

• wlr_weight_1 is constant for log rank test

• wlr_weight_power is Gehan-Breslow and Tarone-Ware weight function.

Usage

wlr_weight_fh(x, arm0, arm1, rho = 0, gamma = 0, tau = NULL)

wlr_weight_1(x, arm0, arm1)

wlr_weight_n(x, arm0, arm1, power = 1)

Arguments

x	analysis time
arm0	an "arm" object defined in npsurvSS package
arm1	an "arm" object defined in npsurvSS package
rho	A scalar parameter that controls the type of test
gamma	A scalar parameter that controls the type of test
tau	A scalar parameter of the cut-off time for modest weighted log rank test
power	A scalar parameter that controls the power of the weight function
