Overview

About

Maintained by Greg VeramendiCRAN page ↗

A flexible framework for estimating factor models with multiple latent variables. Supports linear, probit, ordered probit, and multinomial logit model components. Features include multi-stage estimation, automatic parameter initialization, analytical gradients and Hessians, and parallel estimation. Methods are described in Heckman, Humphries, and Veramendi (2016) doi:10.1016/j.jeconom.2015.12.001, Heckman, Humphries, and Veramendi (2018) doi:10.1086/698760, and Humphries, Joensen, and Veramendi (2024) doi:10.1257/pandp.20241026.

Changes in 1.7.1

Bug fixes

robust_se() now returns a *named* vector, as documented. It previously computed sqrt(pmax(0, diag(V))), and pmax() copies attributes from its first argument (the scalar 0), which dropped the parameter names; name-based indexing of the result then silently returned NA. Fixed by ordering the parameter vector first (sqrt(pmax(diag(V), 0))), with a regression test on the naming contract.

Usability

define_model_component(): covariates now defaults to NULL, so a pure measurement item no longer needs covariates = NULL spelled out. The documentation also makes the factor-assignment convention explicit (the length-n_factors loading_normalization vector: 0 off-factor, 1 anchor, NA free), and adds a factor_index convenience argument for assigning an item to a single factor (factor_index = 2, loading_normalization = 1 is shorthand for c(0, 1, 0) in a 3-factor model).

vcov_factorana() now verifies that the data it is given matches the data the model was fit on (same rows, same order) via a lightweight fingerprint stored on the fit, and errors with a clear message otherwise. This catches the "right shape, wrong rows" case that the free-parameter-count check could not.

Install

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

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

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

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-factorana

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-factorana

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-factorana

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.
