Overview

About

Maintained by Alexander ChristensenCRAN page ↗GitHub ↗Issues ↗

Generates data based on latent factor models. Data can be continuous, polytomous, dichotomous, or mixed. Skews, cross-loadings, wording effects, population errors, and local dependencies can be added. All parameters can be manipulated. Data categorization is based on Garrido, Abad, and Ponsoda (2011) doi:10.1177/0013164410389489.

Changes in 0.0.9

UPDATE: skew range supported by categorize, simulate_factors, and simulate_hierarchical_factors expanded from -2/2 to -10/10 (in increments of 0.05); skew_tables regenerated over the new range
INTERNAL: skew_generator rewritten to compute skewness analytically from category counts instead of materializing a sample_size-length vector and calling psych::skew() on it (mathematically equivalent, since the moment-skewness formula only depends on counts per value); it also now searches adaptively over reduction_factor and sample_size when the defaults can't reach a target skew directly, closing gaps (e.g., skew near zero for categories >= 4) that were previously unreachable regardless of tolerance. Together, this cut full skew-table generation time from tens of minutes to about a second
FIX: skew_generator's bisection search had a typo (limitinf instead of limitsinf) that left the lower search bound frozen at zero, which combined with skew(proportion) not being monotonic across its full domain, could prevent convergence even for reachable targets

From NEWS in the release

Install

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

install.packages("latentFactoR", 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("AlexChristensen/latentFactoR")

Development version from AlexChristensen/latentFactoR. 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-latentfactor

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-latentFactoR

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-latentFactoR

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.
