calc_c

Helper function to calculate allocation ratios from stagewise sample sizes

Methods to calculate optimal design parameters
for one- and two-stage three-arm group-sequential gold-standard
non-inferiority trial designs
with or without binding or nonbinding futility boundaries,
as described in Meis et al. (2023) <doi:10.1002/sim.9630>.
