In ns-ctru/futility: Compute the conditional power of a Randomised Control Trial

Futility - Conditional power calculations for stopping RCTs

This repository contains the R package futility which allows the conditional power of an in-progress Randomised Control Trial (RCT) to be calculated with a view to stopping the trial earlier because of futility (i.e. any further data collected will not alter the conclusions drawn from it). It reports the probability of stopping a study for futility as well as the probability of continuing and finding a non-signicant result.
