%description
Provides tools to assist planning and monitoring of time-to-event trials
under complicated censoring assumptions and/or non-proportional hazards.
There are three main components: The first is analytic calculation of
predicted time-to-event trial properties, providing estimates of expected
hazard ratio, event numbers and power under different analysis methods.
The second is simulation, allowing stochastic estimation of these same
properties. Thirdly, it provides parametric event prediction using blinded
trial data, including creation of prediction intervals. Methods are based
upon numerical integration and a flexible object-orientated structure for
defining event, censoring and recruitment distributions (Curves).
