as Adaptive Group Sequential Trial

Description

Function as.AGST builds an adaptive group sequential trial object

Usage

as.AGST(pT, iD, sT, sTo = NULL)

Arguments

`pT`	object of the `class` `GSTobj`; primary trial design
`iD`	interim data; a list with the variables `T` and `z`; list(T = stage of interim analysis, z = interim z-statistic)
`sT`	object of the `class` `GSTobj`; secondary trial design
`sTo`	secondary trial outcome; a list with the variables `T` and `z`; list(T = stage where trial stops, z = z-statistic at stage where trial stops)

Value

Returns a list containing the pT, iD, sT and sTo with class=AGSTobj
