In holiglm: Holistic Generalized Linear Models

Upper Bound

Description

Set a upper bound on the coefficient of specific covariates.

Usage

upper(kvars)

Arguments

kvars

a named vector giving the upper bounds. The names should correspond to the names of the covariates in the model matrix.

Value

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