primaryBoundary {gsrsb}

Calculate Primary Boundaries, Standard Approach

Description

Primary boundaries calculation of standard (original) OBF and POC.

Usage

primaryBoundary(gammaVec, alpha, type = 1, initIntvl = c(1, 4))

Arguments

gammaVec

a vector of square root of information.

alpha

significance level

type

type of sequential procedure. OBF is 1, POC is 2.

initIntvl

paramter for function uniroot (two numbers)

Value

original OBF and POC boundaries (primary endpoints) (a number, c_(K)).
