The exact distribution of the conditional likelihood-ratio test in instrumental variables regression
Malte Londschien
We derive the exact asymptotic distribution of the conditional likelihood-ratio test in instrumental variables regression under weak instrument asymptotics and for multiple endogen…
A statistician's guide to weak-instrument-robust inference in instrumental variables regression with illustrations in Python
Malte Londschien
We provide an overview of results relating to estimation and weak-instrument-robust inference in instrumental variables regression. Methods are implemented in the ivmodels software…
Domain Generalization and Adaptation in Intensive Care with Anchor Regression
Malte Londschien, Manuel Burger, Gunnar Rätsch +1
The performance of predictive models in clinical settings often degrades when deployed in new hospitals due to distribution shifts. This paper presents a large-scale study of causa…
Machine-Learning-Powered Specification Testing in Linear Instrumental Variable Models
Cyrill Scheidegger, Malte Londschien, Peter Bühlmann
The linear instrumental variable (IV) model is widely used in observational studies, yet its validity hinges on strong assumptions. Classical specification tests such as the Sargan…
