--interactions

Switch

--interactions

Description

Enables interactions with multivariate regression.

Argument and Default Value

No argument. Boolean switch, default: False.

Details

When set, pairwise interaction terms between all features are added to the design matrix before fitting the multiple regression, so the model can capture non-additive effects between features rather than only their independent contributions.
