mptstan

Estimate multinomial processing tree (MPT) models, a model class popular in cognitive psychology, in a Bayesian framework using package brms (i.e., ultimately Stan). This allows specifying models with any type of multivariate normal hierarchical or multilevel structure, including models with single and multiple random effects (i.e., crossed random effects). Model specification can be tailored for each model parameter.

Installation

You can install the development version of mptstan from GitHub with:

# install.packages("devtools")
devtools::install_github("mpt-network/mptstan")

Because mptstan is based on brms and therefore Stan, you will need a C++ compiler to use the package. Installation instructions for a C++ compiler for your operating system can be found here: https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started
