Abstract

We study a generalisation of Simpson reversal (also known as Simpson's paradox or the Yule-Simpson effect) to 2×2×22 \times 2 \times 2 contingency tables and characterise the cases for which it can and cannot occur with two combinatorial-geometric lemmas. We also present a conjecture based on some computational experiments on the expected likelihood of such events.
