SplineCategorical

class superglm.SplineCategorical(spline_name: str, cat_name: str)

Bases: object

Varying-coefficient interaction: spline curve per categorical level.

For each non-base level of the categorical, produces one group of K B-spline columns masked by the level indicator. The base level’s effect is absorbed into the main spline term.
