Changes in version 0.4-3 (2026-02-16) - fixed some no pooling issues that prevented certain models from working. Changes in version 0.4-1 (2020-05-18) - Adapted MPTinR unit tests for no pooling approaches to fail even less with R 4.0.0. Changes in version 0.4-0 (2020-03-28) - Added a NEWS.md file to track changes to the package. - Added within-subjects comparisons of parameter estimates that are stored in column test_within of the results object. - For the Bayesian methods, these comparisons rely on posterior distributions of parameter differences. - For the no-pooling maximum-likelihood methods, comparisons rely on paired t tests. - For the complete-pooling maximum-likelihood method, comparisons rely on the the point estimates of parameters and the estimates of the standard errors of differences calculated from the Hessian matrix. - Changed the default behavior for auto-extending Bayesian models: As of now, chains are only combined if Rhat <= Rhat_max*2-1. An informative message is printed whether chains were combined with earlier draws or not. - Prepared MPTmultiverse for new tibble version.
