Consider the fit of the loglinear model (AC, AM,CM) to Table 15.12 for the survey of high school seniors.

(a) Use the estimated expected frequencies in Table 15.14 to estimate the conditional odds ratios between A and M at each level of C.

(b) Show how to obtain the estimated odds ratio in (a)

fromthe parameter estimates for the model in Table 15.15.

(c) By contrast, what is the estimated conditional odds ratio between A and M for the loglinear model denoted by

(AC,CM)?
