[Question] Is there an example for group sequential testing?

[LibiSC]

Hello. I was looking through the examples. Group sequential testing should be a variant of the sequential example? @iampelle ?

Hi @LibiSC,

The sequential example does do group sequential test along the lines of https://cran.r-project.org/web/packages/ldbounds/index.html.

Ok so in the example the alfa is consumed in the peek for each day and divided from taking the total sample for the spending?. In other words each day counts as a peek?
