There are two main parts of this package: 1) Predictions about the required number of events in a 2-arm survival study from a fixed set of parameters, 2) Predictions about the time when reaching a target level of events from accumulated data analysed at an interim in a blinded survival study. 1) uses an exponential or Weibull model for survival and accrual according to a fixed non linear function. 2) by default uses a Weibull model for survival and either a Poisson process or a non-linear function for accrual. This package is based on earlier work by Christophe Delong and Sally Hollis.
