Fifth, as pointed out by Lessov et al,60 correlated measurement errors could bias our parameter estimates. To examine this possibility, we replaced in our best-fit model the two unique environmental-common factors, with a triangular decomposition (Cholesky) model as per Lessov.60 Inconsistent with the hypothesis that our results were biased, the fit of this Cholesky was much worse than our best-fit model by AIC, BIC, aBIC and DIC criteria.
