Researchers have developed a new kernel-based framework for distributional inference in adaptive experiments. This method addresses the challenge of non-i.i.d. data caused by adaptive treatment assignments, which are common in experiments that adjust based on observed outcomes. The framework utilizes doubly robust RKHS scores and a witness function to compare interventional outcome distributions, offering improved accuracy for detecting both mean shifts and higher-moment differences compared to existing methods that are limited to scalar effects.
