Refer to the loglinear models for Table 6.8.

a. Explain why the fitted odds ratios in Table 6.10 for model (GI, GL, GS, IL, IS, LS) suggest that the most likely case for injury is accidents for females not wearing seat belts in rural locations.

b. Fit model (GLS, GI, IL, IS). Show, using model parameter estimates, that the fitted I-S conditional odds ratio equals 0.44. Show that, for each injury level, the estimated conditional L-S odds ratio is 1.17 for (G = female) and 1.03 for (Gmale). How can you get these using the model parameter estimates? (Hint: Calculate the log odds ratio using the model formula.)
