Of particular interest to the researchers was a question about trust that residents had in the police: Would you say that your level of trust in the police is ... The responses were limited to Very Low, Low, Moderate, High, and Very High. The researchers estimated an ordinal logistic regression model and Brant test, and found the following: INDEPENDENT VARIABLE b BRANT TEST Age (in years) 0.02 4.372 Sex (1 ¼ male, 0 ¼ female) 0.38 8.914 Race (1 ¼ nonwhite, 0 ¼ white) 0.42 12.695 Ever arrested? (1 ¼ yes, 0 ¼ no) 0.67 2.720 Ever reported a crime to the police? (1 ¼ yes, 0 ¼ no) 0.26 5.661 Total 34.362 (a) Calculate the odds ratios for each coefficient, and explain what it means. (b) Test the parallel slopes assumption for the full model and each coefficient. What can you conclude about this model? What would your recommendation be to the researchers about the use of the ordinal logistic regression model? Explain why.
