This repository contains the R code used in the empirical applications presented in Florian Böing-Messing & Joris Mulder (2021) Bayes Factors for Testing Order Constraints on Variances of Dependent Outcomes, The American Statistician, 75:2, 152-161, https://doi.org/10.1080/00031305.2020.1715257. The PIAT.R and reading-recognition.R scripts contain the code for the empirical applications in Sections 5.1 and 5.2 of the paper, respectively. The functions.R script contains helper functions for calculating the Bayes factors and posterior probabilities of the hypotheses.
