model.matrix.gnm: Local Design Matrix for a Generalized Nonlinear Model

Description

This method extracts or evaluates a local design matrix for a generalized nonlinear model

Usage

# S3 method for gnm
model.matrix(object, coef = NULL, ...)

Value

If coef = NULL, the local design matrix with columns corresponding to the non-eliminated parameters evaluated at

coef(object) (extracted from object if possible).

Otherwise, the local design matrix evaluated at coef.

Arguments

object

an object of class gnm.

coef

if specified, the vector of (non-eliminated) coefficients at which the local design matrix is evaluated.

...
