To obtain accurate estimates of the effects of youth risky behaviors and family environment on adult outcomes, different types of regression techniques were utilized for different adult outcomes. Many econometric textbooks provide good discussions of the principles and practice of the regression analyses used in this study, e.g. Greene (2000), Judge, et al (1985). These regression techniques were applied to assess the independent effects of youth risky behaviors and family environment on adult outcomes. By independent effects, we mean the effects after other important factors affecting adult outcomes have been controlled or adjusted. These "effects" are associations between the dependent and independent variables and do not necessarily reflect a causal relationship.
