Chi square goodness of fit indices are all non-significant at the α>.05 level, indicating a lack of divergence of observed values from model parameters. Missing data indicates a poor model fit for all tested models (significant Chi square fit index). Standard errors are not calculable on variance parameters fixed at zero. Model parameter estimates are reported for the best fitting model, while heritability estimates (% variance accounted for) are reported for the base model and the best fitting model. Nested DE models are not fit to the data (see Methods for explanation), so base models indicating genetic variance most often reduced to the AE model.
