Results of these tests are presented in Table 4 for the genetic factors. The three fit statistics were consistent in showing a significant effect of A1 on the three endophenotypes, indicating shared genetic variance among them, for both males and females. The A2 influence on beta was not significant for either sex, indicating little genetic overlap between TF-PC1 and beta beyond what is also common to P3. Among males, only the A1 influence on EXT was significant, indicating shared genetic variance among all three endophenotypes and EXT. Among females, by contrast, the A1 influence on EXT was not significant but the influence of A2 and A3 both were. (The latter effect was somewhat marginal, in that setting this path to 0 resulted in a somewhat smaller value of DIC, although AIC was larger and the likelihood-ratio test was significant.)
