If p is a probability then p /( 1 − p ) is the corresponding odds, and the logit of the probability is the logarithm of the odds ; similarly the difference between the logits of two probabilities is the logarithm of the odds ratio ( R ), thus providing a shorthand for writing the correct combination of odds ratios only by adding and subtracting:
