In keaven/gsDesign: Group Sequential Design

Test - gsSurv

[1] "Asymmetric two-sided group sequential design with non-binding futility bound, 3 analyses, time-to-event outcome with sample size 314 and 57 events required, 90 percent power, 2.5 percent (1-sided) Type I error to detect a hazard ratio of 0.4. Enrollment and total study durations are assumed to be 0.5 and 2 months, respectively. Efficacy bounds derived using a Hwang-Shih-DeCani spending function with gamma = -4. Futility bounds derived using a Hwang-Shih-DeCani spending function with gamma = -2."
