... In a contingency table, if we know that X = 1, the probability that Y = 1 is p11 /(p11 + p12 ). If we know that X = 2, the probability that Y = 1 is p21 /(p21 + p22 ) Therefore if X = 1, the odds of Y = 1 versus Y = 2 are p11 /p12 . Similarly, if X = 2, the odds of Y = 1 versus Y = 2 are p21 /p22 . ...
