class statsmodels.stats.oaxaca.OaxacaResults(results, model_type)[source]

This class summarizes the fit of the OaxacaBlinder model.

Use .summary() to get a table of the fitted values or use .params to receive a list of the values

If a two-fold model was fitted, this will return unexplained effect, explained effect, and the mean gap. The list will be of the following order and type.

unexplained : float
This is the effect that cannot be explained by the data at hand. This does not mean it cannot be explained with more.
explained: float
This is the effect that can be explained using the data.
gap: float
This is the gap in the mean differences of the two groups.

If a three-fold model was fitted, this will return characteristic effect, coefficient effect interaction effect, and the mean gap. The list will be of the following order and type.

characteristic effect : float
This is the effect due to the group differences in predictors
coefficient effect: float
This is the effect due to differences of the coefficients of the two groups
interaction effect: float
This is the effect due to differences in both effects existing at the same time between the two groups.
gap: float
This is the gap in the mean differences of the two groups.

Attributes
