Independence Is Not Always Consistently Testable
Senhan Yao
We study the problem of testing independence between the coordinate processes of a jointly stationary ergodic binary process from finite observations. We prove that no test is poin…

Uniform Testability Implies Asymmetric Testability
Senhan Yao
We prove a filtration-level conversion from uniform fixed-time testing to all-sample one-sided error control and uniform future-tail control. Given an adapted deterministic binary…

Weak but Not Strong Asymptotic Testability
Senhan Yao
We construct two fixed disjoint families of stationary ergodic binary process distributions for which a weakly asymptotically consistent test exists, but no strongly asym…
