model.matrix.gnm {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 class 'gnm'
model.matrix(object, coef = NULL, ...)

Arguments

object

an object of class gnm.

coef

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

...

further arguments.

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.
