  摘要：Randomisation inference (RI) is typically interpreted as testing Fisher's 'sharp' null hypothesis that all unit-level effects are exactly zero. This hypothesis is often criticised as restrictive and implausible, making its rejection scientifically uninteresting. We show, however, that many randomisation tests are also valid for a 'bounded' null hypothesis under which the unit-level effects are all non-positive (or all non-negative) but are otherwise heterogeneous. In addition to being more pla...

• Maxway CRT: improving the robustness of the model-X inference AI翻译

  摘要：The model-X conditional randomisation test (CRT) is a flexible and powerful testing procedure for testing the hypothesis X?Y divide Z. However, it requires perfect knowledge of X divide Z and may lose its validity when there is an error in modelling X divide Z. This problem is even more severe when Z is of high dimensionality. In response to this, we propose the Maxway CRT, which learns the distribution of Y divide Z and uses it to calibrate the resampling distribution of X to gain robustness ...
• Prediction sets adaptive to unknown covariate shift AI翻译

  摘要：Predicting sets of outcomes-instead of unique outcomes-is a promising solution to uncertainty quantification in statistical learning. Despite a rich literature on constructing prediction sets with statistical guarantees, adapting to unknown covariate shift-a prevalent issue in practice-poses a serious unsolved challenge. In this article, we show that prediction sets with finite-sample coverage guarantee are uninformative and propose a novel flexible distribution-free method, PredSet-1Step, to ...
