Table 7.17 is from a General Social Survey. White subjects in the sample were asked: (B) Do you favor busing (Negro/Black) and white school children from one school district to another?, (P) If your party nominated a (Negro/Black) for President, would you vote for him if he were qualified for the job?, (D) During the last few years, has anyone in your family brought a friend who was a (Negro/Black) home for dinner? The response scale for each item was (1 = Yes, 2 = No or Do not know). Table 7.18 shows output from fitting model (BD, BP, DP). Estimates equal 0 at the second category for any variable.
a. Analyze the model goodness of fit. Interpret.
b. Estimate the conditional odds ratios for each pair of variables. Interpret.
c. Show all steps of the likelihood-ratio test for the BP association, including explaining which loglinear model holds under the null hypothesis. Interpret.
d. Construct a 95% confidence interval for the BP conditional odds ratio. Interpret.
