param: Extract All Parameters from a Model --- Generic Function

Description

This function extracts all parameters (regression coefficients, variance parameters etc.) from a fitted model.

Usage

param(object, …)

Arguments

object

any fitted model object from which parameters may be extracted.

…

additional arguments like digits to control how many digits should be printed.

Value

all parameters (regression coefficients, variance parameters etc.) of a fitted model.

Details

This function is generic (see methods); method functions can be written to handle specific classes of data. Classes which already have methods for this function include: nlreg.
