Overview

About

Maintained by Erik ForsbergCRAN page ↗GitHub ↗Issues ↗

For identifying, estimating, and plotting descriptive multidimensional item response theory models, restricted to 2D and 3D and dichotomous or polytomous data that fit the two-parameter logistic model or the graded response model. The method is primarily exploratory and centered on the plot function, which exposes item characteristics and constructs, represented by vector arrows, within a three-dimensional interactive latent space. The results can be useful for item-level analysis as well as test development.

Changes in 2.1.0

D2mirt function and plot method implented for 2D modeling
Information function introduced for information and standard error analysis
Test units expanded to cover new functions
Vignette and Readme updated to cover new functions and methods
Test data set includes angles3D for D3mirt() function and angles2D for D3mirt() function
Color option for construct vectors implemented in plot methods
Minor updates include:
Dots in D3mirt and D2mirt for additional arguments
Argument ind.scores changed to scores
Argument construct.lab is abbreviated to c.lab

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("D3mirt", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("ForsbergPsychometrics/D3mirt")

Development version from ForsbergPsychometrics/D3mirt. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-d3mirt

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-D3mirt

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-D3mirt

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
