Conditional odds ratios are odds ratios between two variables for fixed levels of the third variable and allow us to test for conditional independence of two variables, given the third. For example, for the fixed level Z = k, the conditional odds ratio between X and Y is. θ X Y ( k) = μ 11 k μ 22 k μ 12 k μ 21 k.
