User-friendly analysis of hierarchical multinomial processing tree (MPT)
models that are often used in cognitive psychology. Implements the latent-trait
MPT approach (Klauer, 2010) <doi:10.1007/s11336-009-9141-0> and the beta-MPT
approach (Smith & Batchelder, 2010) <doi:10.1016/j.jmp.2009.06.007> to model
heterogeneity of participants. MPT models are conveniently specified by an
.eqn-file as used by other MPT software and data are provided by a .csv-file
or directly in R. Models are either fitted by calling JAGS or by an MPT-tailored
Gibbs sampler in C++ (only for nonhierarchical and beta MPT models). Provides
tests of heterogeneity and MPT-tailored summaries and plotting functions.
A detailed documentation is available in Heck, Arnold, & Arnold (2018)
<doi:10.3758/s13428-017-0869-7> and a tutorial on MPT modeling can be found
in Schmidt, Erdfelder, & Heck (2023) <doi:10.1037/met0000561>.
