Note: A1, C1, E1 represent common ACE effects on Math, WD, and RC; A2, C2, E2 represent ACE effects on WD and RC that are independent of Math; A3, C3, E3 represent ACE effects on RC that are independent of both Math and WD. The proportion of variance due to A, C, E (in boldface) can be obtained by summing the squared estimates from the Cholesky decomposition analysis.
