grpl.model-class: Class "grpl.model": Group Lasso Models

Description

Objects of class "grpl.model" define link function, negative log-likelihood and corresponding gradient and Hessian for the model to be used in a group lasso problem.

Objects from the Class

Objects can be created by calls of the form grpl.model(...)
