%description
Predict the course of clinical trial with a time-to-event endpoint for
both two-arm and single-arm design. Each of the four primary study design
parameters (the expected number of observed events, the number of subjects
enrolled, the observation time, and the censoring parameter) can be
derived analytically given the other three parameters. And the simulation
datasets can be generated based on the design settings.
