Fittings and likelihood of various models tested in the L. IFG.

Percent signal changes in the L. IFG were fitted with a single scale parameter to a model of each factor using its subtracted estimates (Table 1) for Simple – Match, Linear – Match, and Quad – Match. The P-values for the t-tests between the fitted value for each contrast and individual activations are shown in ascending order. Note that the model of DoM in the hierarchical tree structures (with an asterisk) resulted in the best fit for this region, i.e., with the least residual sum of squares (RSS), largest coefficient of determination (r2), and larger P-values. The likelihood of models with all null estimates was not calculable (n/a). A likelihood ratio is the ratio of each model's likelihood to the best model's likelihood. The best model of DoM in the hierarchical tree structures was by far more likely than the other models.Fittings and likelihood of various models tested in the L. IFG.
