pSeqStop {eva}

P-Value Sequential Adjustment

Description

Given a set of (ordered) p-values, returns p-values adjusted according to the ForwardStop and StrongStop stopping rules.

Usage

pSeqStop(p)

Arguments

p

Vector of ordered p-values.

Details

Roughly speaking, under the assumption of independent but ordered p-values, the StrongStop adjusted p-values control for the familywise error rate, while ForwardStop provides control for the false discovery rate.

Value

StrongStop

Vector of ordered p-values adjusted for the familywise error rate.

ForwardStop

Vector of ordered p-values adjusted for the false discovery rate.

UnAdjusted

Vector of non-transformed p-values.
