Post-Selection Inference for Generalized Lasso after Optimal Transport-based Domain Adaptation

PSI-GLAD is a Python package that implements a selective inference (SI) framework for conducting valid statistical inference after generalized lasso (GL) in the presence of domain adaptation (DA). The main idea is to leverages the SI framework and employs a divide-and conquer approach to efficiently compute the $p$ -value. Our proposed methods provides valid $p$-value for GL-DA results, by keeping the false positive rate (FPR) under control, while also maximizing the true positive rate (TPR), i.e., lowering the false negative rate (FNR).
