Novometric statistical analyses were used to model smoking habits of one’s male friends, and of one’s female friends, for samples of 3,289 Anglo-American, 944 Mexican-American, and 733 Indian-American college undergraduates. For both analyses the categorical attributes were ethnicity (a multicategorical attribute, dummy-coded using 1-3, respectively), and subject gender (0=female, 1=male) and smoking behavior (0=non-smoker, 1=smoker). The novometric findings are compared with results originally reported for this application obtained using disintegrated chi-square analysis.
