Figure 2

At a given point on the abscissa in panel B, the ordinate positions of each curve sum to unity. SES is a composite of parental educational attainment, parental occupational status, and household income, transformed to cumulative proportions (mean = 0.58, SD = 0.24). Model #15 included A × SES and E × SES effects.
