New framework offers optimal sequential testing for Markovian data

Researchers have developed a new framework for sequential hypothesis testing specifically designed for data generated by Markov chains. This framework establishes a non-asymptotic lower bound on the expected stopping time for any valid sequential test, which is shown to be asymptotically tight. The proposed optimal test achieves this lower bound, offering a sharp characterization of optimal sequential testing procedures under Markovian dependence. Applications include detecting model misspecification in Markov Chain Monte Carlo and testing structural properties in Markov decision processes. AI
