GroupSeq: A GUI-Based Program to Compute Probabilities Regarding Group Sequential Designs

Share:

A graphical user interface to compute group sequential designs based on normally distributed test statistics, particularly critical boundaries, power, drift, and confidence intervals of such designs. All computations are based on the alpha spending approach by Lan-DeMets with various alpha spending functions being available to choose among.
