Description

Uses standard MPT files in the .eqn-format (Moshagen, 2010) to fit hierarchical Bayesian MPT models. Note that the software JAGS is required (http://mcmc-jags.sourceforge.net).

The core functions either fit a Beta-MPT model (betaMPT; Smith & Batchelder, 2010) or a latent-trait MPT model (traitMPT; Klauer, 2010). A fitted model can be inspected using convenient summary and plot functions tailored to hierarchical MPT models.

Detailed explanations and examples can be found in the package vignette, accessible via vignette("TreeBUGS")
