The -test: Increasing the Linear Model -test's Power Under Sparsity Without Sacrificing Validity

Danielle Paulson, Souhardya Sengupta, Lucas Janson

We introduce a new procedure for testing the significance of a set of regression coefficients in a Gaussian linear model with . Our method, the -test, provides the sam…

Chiseling: Powerful and Valid Subgroup Selection via Interactive Machine Learning

Nathan Cheng, Asher Spector, Lucas Janson

In regression and causal inference, controlled subgroup selection aims to identify, with inferential guarantees, a subgroup (defined as a subset of the covariate space) on which th…

The Relative Instability of Model Comparison with Cross-validation

Alexandre Bayle, Lucas Janson, Lester Mackey

Cross-validation (CV) is known to provide asymptotically exact tests and confidence intervals for model improvement but only when the model comparison is relatively stable. Surpris…

Semiparametric Inference for Partially Identifiable Data Fusion Estimands via Double Machine Learning

Yicong Jiang, Lucas Janson

Many statistical estimands of interest (e.g., in regression or causality) are functions of the joint distribution of multiple random variables. But in some applications, data is no…

Optimal ablation for interpretability

Maximilian Li, Lucas Janson

Interpretability studies often involve tracing the flow of information through machine learning models to identify specific model components that perform relevant computations for…

The -test: leveraging sparsity in the Gaussian linear model for improved inference

Souhardya Sengupta, Lucas Janson

We develop novel LASSO-based methods for coefficient testing and confidence interval construction in the Gaussian linear model with . Our methods' finite-sample validity is…

Total Variation Floodgate for Variable Importance Inference in Classification

Wenshuo Wang, Lucas Janson, Lihua Lei +1

Inferring variable importance is the key problem of many scientific studies, where researchers seek to learn the effect of a feature on the outcome in the presence of confo…

Effective Degrees of Freedom: A Flawed Metaphor

Lucas Janson, William Fithian, Trevor Hastie

To most applied statisticians, a fitting procedure's degrees of freedom is synonymous with its model complexity, or its capacity for overfitting to data. In particular, it is often…
