Overview

About

Maintained by Connor JerzakCRAN page ↗GitHub ↗Issues ↗

Implements methods for analyzing latent variable models with measurement error correction, including Item Response Theory (IRT) models. Provides tools for various correction methods such as Bayesian Markov Chain Monte Carlo (MCMC), over-imputation, bootstrapping for robust standard errors, Ordinary Least Squares (OLS), and Instrumental Variables (IV) based approaches. Supports flexible specification of observable indicators and groupings for latent variable analyses in social sciences and other fields. Methods are described in a working paper (2025) doi:10.48550/arXiv.2507.22218.

Changes in 1.1.4

Package Rename

Renamed package from lpme to lpmec (Latent Predictor Measurement Error Correction).
The name "lpme" was already taken by a different archived CRAN package (by Zhou & Huang).
Main functions are lpmec() and lpmec_onerun().

CRAN Resubmission

Removed dependency on archived package decon.
Version bump from 0.1.1 to 1.1.4 (continuing from archived CRAN version 1.1.3).

CRAN Preparation

Fixed vignette to use correct estimation_method values ("em" instead of "emIRT").
Added .Rbuildignore to exclude development files from package build.
Replaced eval(parse()) pattern with direct assignment for CRAN compliance.
Changed F/T to FALSE/TRUE throughout codebase.

Show all changes in 1.1.4Hide the rest of the changes in 1.1.4

Wrapped examples in \donttest{} to avoid CRAN timeout issues.
Changed conda_env_required default to FALSE for CRAN compatibility.
Updated CITATION file to use modern bibentry() format.
Added skip_on_cran() guards to test files.
Added internal function documentation with @noRd tags.

Documentation

Fixed documentation to correctly indicate pscl as the default MCMC backend.
Updated version year in CITATION file.

Previous Changes

Added CITATION file for proper citation information.
Updated DESCRIPTION with explicit Author field.
Minor documentation updates.

Install

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

install.packages("lpmec", 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("cjerzak/lpmec-software")

Development version from cjerzak/lpmec-software. 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-lpmec

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-lpmec

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-lpmec

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.
