1.1 The Project

This document contains the verification of the results computed in JASP. For this purpose, the same statistical tests have been performed on the same datasets, using the most popular statistical software packages and hand calculations. The comparison of the output is available for each test in the following chapters.

The software packages that have been used for comparison are:

Software Version
JASP 0.13.1
SPSS 26.0.0
SAS 3.8 (Basic Edition)
Minitab 19.2020.1
R 4.0.2

All code used for computation is available in this document. The datasets used can be found in the Github repository of this project: https://github.com/jasp-stats/jasp-verification-project
