Fisherian and Neymanian Methods for Detecting and Measuring Treatment Effect Variation
Description
This package implements methods developed by Ding, Feller, and Miratrix (JRSS-B, 2016) "Randomization Inference for Treatment Effect Variation", for validly testing whether there is unexplained variation in treatment effects across observations. The package also implements methods introduced in Ding, Feller, and Miratrix (JASA, 2019) "Decomposing Treatment Effect Variation", for measuring the degree of treatment effect heterogeneity explained by covariates. The package includes wrapper functions implementing the proposed methods, as well as helper functions for analyzing and visualizing the results of the tests.
