Table 4 does not include similar statistics for the nonshared environmental effects. Because E includes measurement error as well as other sources of nonshared influence, the paths from each E to its corresponding phenotype (E1 on P3, E2 on TF-PC1, E3 on beta, and E4 on EXT) cannot be deleted. Constraining the remaining paths indicated that E1, the latent factor common to all phenotypes, had a significant influence on TF-PC1 in both males, Δχ2 = 170.5, p < .001, AIC = 11795.5, DIC = 11961.6, and females, Δχ2 = 223.1, p < .001, AIC = 11848.1, DIC = 12014.1. Among males, there was also a marginally significant effect of E1 on EXT, Δχ2 = 4.6, p = .032, AIC = 11629.6, DIC = 11795.6. (The latter actually represented a small decrease, indicating better fit.) None of the other paths was significant, with all chi-squared values less than or equal to 1.4.
