In lrstat: Power and Sample Size Calculation for Non-Proportional Hazards and Beyond

Adjusted p-Values for Simes-Based Graphical Approaches

Description

Obtains the adjusted p-values for graphical approaches using weighted Simes tests.

Usage

fadjpsim(p, wgtmat = NULL, family = NULL)

Arguments

p	The raw p-values for elementary hypotheses.
wgtmat	A list containing the weight matrix and the indicator matrix for intersection hypotheses. If NULL, equal weights are assigned within each intersection hypothesis.
family	The matrix of family indicators for elementary hypotheses. Defaults to one family containing all elementary hypotheses.

Value

A list with the following components:

• inthyp: The indicator matrix for the intersection hypotheses.

• pinter: The local p-values for the intersection hypotheses.

• padj: The adjusted p-values for the elementary hypotheses.
