Overview

About

Maintained by Charles CoverdaleCRAN page ↗GitHub ↗Website ↗Issues ↗

Implements tests for the identifying assumptions of instrumental variable models, the local exclusion restriction and monotonicity conditions required for local average treatment effect identification. Covers Kitagawa (2015) doi:10.3982/ECTA11974, Mourifie and Wan (2017) doi:10.1162/REST_a_00622, and Frandsen, Lefgren, and Leslie (2023) doi:10.1257/aer.20201860. Includes a one-shot wrapper that runs all applicable tests on a fitted instrumental variable model. Dispatches on 'fixest' and 'ivreg' model objects.

Changes in 0.1.2

Bug fix (behaviour change)

iv_kitagawa() dispatched on a fitted fixest or ivreg model with exogenous controls used to silently drop the controls and return the unconditional test. This was wrong when validity is only conditional on X. The fitted-model methods now error and direct the user to iv_mw() for the conditional Mourifie-Wan (2017) test, or to the raw-vector default method to force an unconditional test on the same data.
iv_check() now filters its applicable-tests list by the presence and dimensionality of exogenous controls. Kitagawa is dropped when any control is present; Mourifie-Wan is dropped when more than one control is present (multivariate X is planned for v0.2.0 via a tensor-product series basis). When a test is dropped, iv_check() emits an informational message explaining why.

Show all changes in 0.1.2Hide the rest of the changes in 0.1.2

iv_check() no longer falls back to running Mourifie-Wan unconditionally when handed a model with multivariate controls. That downgrade was the same silent-drop bug as the Kitagawa one.

Documentation

vignette("with-fixest") rewritten to demonstrate the new behaviour: the unconditional case, the single-control conditional path through iv_mw(), and the multivariate workaround (propensity-index dimension reduction).

Install

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

install.packages("ivcheck", 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("charlescoverdale/ivcheck")

Development version from charlescoverdale/ivcheck. 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-ivcheck

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-ivcheck

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-ivcheck

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.
