Using data from a representative sample of 5,952 adults in New York State, CART (Classification and Regression Trees) methodology was used to classify abstainers and drinkers according to interactions among 10 sociodemographic characteristics. A CART analysis classifying abstainers versus drinkers selected income at $25,000 for the initial split with high rates of drinking among higher income individuals. Low rates of drinking were shown for low income women with less than a high school education. A second CART analysis was performed for drinkers only, revealing a number of subgroups of heavier drinkers, including non-Jewish, non-Oriental men under 35 years old and never-married or divorced minority women over the age of 24.
利用来自纽约州5952名成年人的代表性样本数据，采用分类回归树（CART）方法，根据10种社会人口学特征之间的相互作用对戒酒者和饮酒者进行分类。一项将戒酒者与饮酒者进行分类的CART分析选择了25000美元的收入作为初始划分标准，高收入人群的饮酒率较高。受教育程度低于高中的低收入女性饮酒率较低。仅对饮酒者进行了第二次CART分析，结果显示了一些重度饮酒者的亚组，包括35岁以下的非犹太、非东方男性以及24岁以上未婚或离异的少数族裔女性。
