ivcheck: Tests for Instrumental Variable Validity in R
Published:
Abstract
Tests whether an instrumental variable is doing the job we hope it is. Implements three published falsification tests for the identifying assumptions behind local average treatment effects. A one-shot wrapper inspects a fitted IV model, picks the applicable tests, and returns a tidy verdict table.
