Perform a bayesian estimation of the Exploratory reduced Reparameterized Unified Model (‘ErRUM’) described by Culpepper and Chen (2018) doi:10.3102/1076998618791306.

Installation

You can install errum from CRAN using:

install.packages("errum")

Or, you can be on the cutting-edge development version on GitHub using:

if(!requireNamespace("devtools")) install.packages("devtools")
devtools::install_github("tmsalab/errum")

Usage

To use the errum package, load it into R using:

library("errum")

From there, the errum model can be estimated using:

errum_model = errum(<data>, chain_length = 10000)

Authors

James Joseph Balamuta, Steven Andrew Culpepper, and Jeffrey A. Douglas
