k_max {holiglm}

Constraint on the Number of Covariates

Description

Constraint on the maximum number of covariates to be used in the model.

Usage

k_max(k)

Arguments

k

an positive integer with k \leq k_{max} giving the maximum number of covariates to be used in the model.

Value

A holistic generalized model constraint, object inheriting from class "hglmc".

Note

• If an intercept is used, the upper bound on k_{max} + 1 is given by number of columns of the model matrix.

• If no intercept is used, the upper bound on k_{max} is given by number of columns of the model matrix.
