rmBayes: Performing Bayesian Inference for Repeated-Measures Designs
Zhengxiao Wei, Farouk S. Nathoo, Michael E. J. Masson · 2021
A Bayesian credible interval is interpreted with respect to posterior probability, and this interpretation is far more intuitive than that of a frequentist confidence interval. However, standard highest-density intervals can be wide due to between-subjects variability and tends to hide within-subject effects, rendering its relationship with the Bayes factor less clear in within-subject (repeated-measures) designs. This urgent issue can be addressed by using within-subject intervals in within-subject designs, which integrate four methods including the Wei-Nathoo-Masson (2023) , the Loftus-Masson (1994) , the Nathoo-Kilshaw-Masson (2018) , and the Heck (2019) interval estimates.
