WebMar 7, 2024 · The CMH analysis for a two-way table produces generalized Cochran-Mantel-Haenszel statistics (Landis etal., 1978). These include the CMH correlation statistic ( "cor" ), treating both factors as ordered. For a given statum, with equally spaced row and column scores, this CMH statistic reduces to (n-1) r^2 , where r is the Pearson correlation ...

It is most commonly used with 2x2xK tables, where K is the number of measurement conditions.
WebNote also that fisher.test() in R for \(2 \times 2\) tables will give so-called "conditional estimate" of the odds-ratio so the value will be different (in this case, approximately 6.408). Notice the difference between the exact and asymptotic CIs for the odds ratio for the two-sided alternative (e.g., \(\theta\ne1\)). The exact version is larger.
