Note. Parameters reported are standardized path estimates and standard errors are given in parentheses. Model 1 estimated study-specific p and g ACE estimates and correlations. Model 2 estimated study-specific ACE estimates and study-averaged ACE correlations. Model 3a estimated study-averaged ACE estimates for p and crosstrait ACE correlations. Model 3b estimated study-averaged ACE estimates for g and cross-trait ACE correlations.
