modelbpp: Model BIC Posterior Probability

(Version 0.2.0 updated on 2026-03-01, release history)

This package is for assessing model uncertainty in structural equation modeling (SEM) by the BIC posterior probabilities of the fitted model and its neighboring models, based on the method presented in Wu, Cheung, and Leung (2020). The package name, modelbpp, stands for model bayesian posterior probability. An introduction to the package can be found in the following article:
