^aProbabilities are computed from estimates reported in Table 5. All models hold Table 1 child and family characteristics constant at their means. Models 2-7 successively adjust for age 7 educational performance; age 11 performance; educational tracking; educational expectations; age 16/18 performance; and smoking in earlier adulthood, at age 23.
