Table values show logit estimates adjusted for parents’ education and income and respondent’s age, sex, race, education (at Wave IV), and income (at Wave IV). Test shown tests the equivalence of the logit coefficients, that is, ln(OS/SS) = 0. Effect size reports standard mean difference following Chinn [23].
