statsmodels.othermod.betareg.BetaResults.get_distribution_params

BetaResults.get_distribution_params(exog=None, exog_precision=None, transform=True)

Return distribution parameters converted from model prediction.

Parameters:

• params (array_like) – The model parameters.

• exog (array_like) – Array of predictor variables for mean.

• transform (bool) – If transform is True and formulas have been used, then predictor exog is passed through the formula processing. Default is True.

Returns:

(alpha, beta) – Parameters for the scipy distribution to evaluate predictive distribution.

Return type:

tuple of ndarrays
