In triggerstrategy: Trigger Strategy in Clinical Trials

Type I error rate of the overall null hypothesis using the partial hierarchical design

Description

This function computes the type I error rate of the overall null hypothesis using the partial hierarchical group sequential design.

Usage

sErrRphInt2(cvec0, cvec1, t0, t1, tc0 = t0, tc1 = t1, rho = 0)

Arguments

cvec0	a vector of critical boundaries for testing H0
cvec1	a vector of critical boundaries for testing H1
t0	a vector of information times for H0
t1	a vector of information times for H1
tc0	a vector of calendar times for H0
tc1	a vector of calendar times for H1
rho	a value of the correlation between the test statistics for H0 and H1.

Value

a number shows the type I error rate of testing H0 intersect H1
