Likelihood-Free Frequentist Inference: Bridging Classical Statistics and Machine Learning for Reliable Simulator-Based Inference
We introduce Likelihood-Free Frequentist Inference (LF2I), a framework that bridges classical statistics and machine learning for valid confidence sets in complex, likelihood-free settings. LF2I provides confidence sets with near finite-sample validity and offers practical diagnostics for empirical coverage, ensuring reliable scientific inference without costly Monte Carlo or bootstrap methods.
