SPT: SPHERE Psychometrics Tools

R package for psychometrics modeling using Rasch Measurement Theory (RMT). This package focuses on cross-sectional RMT modeling, statistical inference, DIF analysis and causal inference.

SPT uses utilities from various other software to function. Please cite these when using SPT:

  • R package vcrpart for Marginal Maximum Likelihood (MML) estimation of Rasch family models as mixed-effects ordinal regression models
  • R package PP for a posteriori person parameter estimation
  • JAGS and R packages rjags and dclone for MCMC estimation of bayesian models

The primary aim of SPT is to implement features of RMT that are currently unavailable in R, including model estimation with DIF parameters, iterative DIF detection methods and causal inference methods for RMT models.

Please note that SPT is currently under active development and is thus incomplete and may contain bugs. Please check this repository regularly for updates and open an issue and/or submit a pull request if you encounter any problem.

Installation

Install dependencies and the devtools package required for installation:

install.packages("vcrpart","rjags","dclone","PP","devtools")

Please note you also need to install git and RTools to install SPT. In order to run bayesian models, please also install JAGS.

Then, install SPT:

devtools::install_git("https://git.corentinchoisy.xyz/corentinchoisy/SPT.git")

Upgrading

# If SPT is currently loaded in your environment
detach("package:SPT",unload=T)
devtools::install_git("https://git.corentinchoisy.xyz/corentinchoisy/SPT.git")
