OptOTrials: Optimal Two-Stage Designs for Ordered Categorical Outcomes

Functions to design and simulate optimal two-stage randomized controlled trials (RCTs) with ordered categorical outcomes, supporting rank-based tests and group-sequential decision rules. Methods build on classical and modern rank tests and two-stage/Group-Sequential designs, e.g., Park (2025) <doi:10.1371/journal.pone.0318211>. Please see the package reference manual and vignettes for details.
