param_pi2_rates

A numeric value that represents the assumed probability in the reference group if two treatment 
groups are considered, default is <code>0.2</code>.

Parameter Description: Pi (2) for Rates

internal

Design and analysis of confirmatory adaptive clinical trials with continuous, binary, and survival endpoints according to the methods described in the monograph by Wassmer and Brannath (2016) <doi:10.1007/978-3-319-32562-0>. This includes classical group sequential as well as multi-stage adaptive hypotheses tests that are based on the combination testing principle.
