Implements the latent-trait MPT approach (Klauer,\n2010) and the beta-MPT approach\n(Smith & Batchelder, 2010) to\nmodel heterogeneity of participants. MPT models are\nconveniently specified by an .eqn-file as used by other MPT\nsoftware and data are provided by a .csv-file or directly in R.\nModels are either fitted by calling JAGS or by an MPT-tailored\nGibbs sampler in C++ (only for nonhierarchical and beta MPT\nmodels). Provides tests of heterogeneity and MPT-tailored\nsummaries and plotting functions. A detailed documentation is\navailable in Heck, Arnold, & Arnold (2018)\n and a tutorial on MPT modeling\ncan be found in Schmidt, Erdfelder, & Heck (2023)\n.", "License": "GPL-3", "Encoding": "UTF-8", "URL": "https://github.com/danheck/TreeBUGS", "LazyData": "TRUE", "Config/roxygen2/version": "8.0.0", "Config/pak/sysreqs": "jags pari-gp", "Repository": "https://danheck.r-universe.dev", "Date/Publication": "2026-05-07 00:53:42 UTC", "RemoteUrl": "https://github.com/danheck/treebugs", "RemoteRef": "HEAD", "RemoteSha": "8601a71e6d820e01f0ba25a50ce650238e263f37", "Packaged": { "Date": "2026-07-06 10:35:23 UTC", "User": "root" }, "Author": "Daniel W.
