Package: GroupSeq 1.4.4

GroupSeq: Group Sequential Design Probabilities - With Graphical User Interface

Computes probabilities related to group sequential designs for normally distributed test statistics. Enables to derive critical boundaries, power, drift, and confidence intervals of such designs. Supports the alpha spending approach by Lan-DeMets (1994) <doi:10.1002/sim.4780131308>.
