Article mentions the efficiency gap metric; here is another: "Assessing significance in a Markov chain without mixing" We present a new statistical test to detect that a presented state of a reversible Markov chain was not chosen from a stationary distribution... We illustrate the use of our test with a potential application to the rigorous detection of gerrymandering in Congressional districtings. https://arxiv.org/abs/1608.02014 https://arxiv.org/abs/1608.02014
