Update Release Notes
This page lists the changes that have been made to PASS 2022 since it was released.
Released: February 14, 2022
1. Modified the allowable ranges for Cluster Size parameters M and m in the three Stepped-Wedge Cluster-Randomized Design procedures. The restriction that both parameters be ≥ 2 was found to be unnecessary. Now both parameters have allowed range of > 0.
2. An error in the “Mann-Whitney or Wilcoxon Rank-Sum Tests (Simulation)” and the “Tests for Two Means (Simulation)” routines has been corrected. The error caused the mean differences to be reported incorrectly in cases where the distribution’s first parameter was not the mean. The power calculations were correct.
