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)).
