statsmodels.othermod.betareg.BetaResults.get_influence¶
- BetaResults.get_influence()[source]¶
Get an instance of MLEInfluence with influence and outlier measures
- Returns:¶
- infl
MLEInfluence
instance
The instance has methods to calculate the main influence and outlier measures as attributes.
- infl
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.
