9.4 Use the 2006 GSS data set to predict whether a respondent favors the death penalty for murder (CAPPUN) from the respondent’s sex (SEX) and race (RACE) as well as their interaction.
a. Use the likelihood ratio test to test the interaction between SEX and RACE. Report and fully interpret the results from a substantive perspective.
b. If one were to fit a log-linear model using all three variables (CAPPUN, SEX, and RACE), what model comparison would be equivalent to the one performed in part
(a)? Explain why these model comparisons are conceptually equivalent: What does the model comparison represent in each case (logistic/log-linear)?
