Notes

Support for mutli-link and multi-exog models is still experimental in MLEInfluence. Interface and some definitions might still change.

Note: Difference to R betareg: Betareg has the same general leverage as this model. However, they use a linear approximation hat matrix to scale and studentize influence and residual statistics. MLEInfluence uses the generalized leverage as hat_matrix_diag. Additionally, MLEInfluence uses pearson residuals for residual analusis.
