After obtaining estimates of the A and E parameters of the Cholesky decomposition model, the estimated Cholesky path coefficients were converted and rescaled into A and E correlation matrices for the 22 variables, which then served as the input to exploratory factor analyses performed in Mplus 5.21. Exploratory factor analyses were conducted using an unweighted least squares estimator because of the nonpositive definite properties of the A and E correlation structures. The geomin rotation method in Mplus was used to obtain the oblique rotation of the chosen exploratory factor analysis solution. We used oblique rotations because we wanted to examine the magnitude of the relationship between the resulting genetic and environmental factors.
