POSSA: Power Simulation for Sequential Analyses and Multiple Hypotheses
Calculates, via simulation, power and appropriate stopping
alpha boundaries (and/or futility bounds) for sequential analyses (i.e.,
group sequential design) as well as for multiple hypotheses (multiple tests
included in an analysis), given any specified global error rate. This enables
the sequential use of practically any significance test, as long as the
underlying data can be simulated in advance to a reasonable approximation.
