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)).
