Three stage group sequential adaptive design with subgroup selection

Description

ASSISTant is a package that implements a three-stage adaptive clinical trial design with provision for subgroup selection where the treatment may be effective; see Lai, Lavori and Liao (doi:10.1016/j.cct.2014.09.001). The main design object is an R6 class that can be instantiated and manipulated to obtain the operating characteristics. A vignette is provided showing the use of this package for designing the DEFUSE-3 trial, described in the paper by Lai, Lavori and Liao. The package contains everything necessary to reproduce the results of the paper.
