Optimal Allocations in Platform Trials

Optimal Allocations in Platform Trials

This app computes optimal allocation ratios in Period 2 of a platform trial with two experimental and one control arm. In Periods 1 and 2 the optimal allocation is in all cases 1:1 allocation.

For details see Bofill et al. (2022)
