Two new arXiv papers explore the concept of Prediction-Powered Inference (PPI), a framework that uses machine learning predictions to improve statistical inference when outcomes are difficult to measure. The first paper, "Optimal Inference with Black-box Predictions," focuses on the high-dimensional Gaussian sequence model, characterizing theoretical limits and developing practical hypothesis tests. The second paper, "Demystifying Prediction Powered Inference," synthesizes existing PPI variants, offering a unified workflow for practitioners. It highlights that while PPI can yield tighter confidence intervals, reusing training data can lead to anti-conservative results, and under certain missing data conditions, all methods may produce biased estimates.
