Update Release Notes

This page lists the changes that have been made to PASS 2022 since it was released.

Version: 22.0.2

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.

Version: 22.0.1

Released: January 28, 2022

1. Initial Release of PASS 2022.

I have used several statistics tools, but NCSS is the best statistics tool. It is easy to use because the interface and menu are easy to be used. And NCSS is very useful to support an analysis [in] data research.

Evi Triandini, Researcher

"The NCSS software is and has always been the best solution for my work as an assessor. I have been exposed to many other analytical and statistical software applications and have found there is no other product on the market that can match the ease of learning, comprehension of function, and the frugality of price the NCSS product offers..."
