BinGSD - Calculate Boundaries and Conditional Power for Single Arm Group
Sequential Test with Binary Endpoint
Consider an at-most-K-stage group sequential design with
only an upper bound for the last analysis and non-binding lower
bounds.With binary endpoint, two kinds of test can be applied,
asymptotic test based on normal distribution and exact test
based on binomial distribution. This package supports the
computation of boundaries and conditional power for single-arm
group sequential test with binary endpoint, via either
asymptotic or exact test. The package also provides functions
to obtain boundary crossing probabilities given the design.
