A parallel set of analyses was conducted for the E covariance structure in Table 2, allowing A to correlate freely. As reported in see Table 4, a 3 higher order factor model like that for A fit best, but as shown in Figure 2, for 8 of the 11 psychopathology phenotypes the majority of E was unique (not shared with other dimensions). Exceptions are ODD, which shares half of its E variance with the higher-order factors, and MDD and GAD, which are the only two dimensions with high loadings on the global factor.
