Refer to model (5.5.2). At width = 20 cm, find the predicted probabilities of a satellite for the colors medium dark and dark. Find the odds for each, and show that the odds ratio equals exp(1.106) = 3.02. When each probability is close to zero, the odds ratio is similar to the ratio of probabilities, providing another interpretation for logistic regression parameters. For widths at which it is small, the predicted probability for medium-dark crabs is about three times that for dark crabs.
