PWEALL (1.2.1)

Design and Monitoring of Survival Trials Accounting for Complex Situations.

Calculates various functions needed for design and monitoring survival trials accounting for complex situations such as delayed treatment effect, treatment crossover, non-uniform accrual, and different censoring distributions between groups. The event time distribution is assumed to be piecewise exponential (PWE) distribution and the entry time is assumed to be piecewise uniform distribution. As compared with Version 1.1.0, this version includes the calculation of the restricted mean survival time and weighted log-rank statistics.
