param {nlreg}

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.

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.

Value

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

Examples

data(metsulfuron)
metsulfuron.nl <- 
    nlreg( log(area) ~ log( b1+(b2-b1) / (1+(dose/b4)^b3) ), 
           weights = ~( 1+dose^exp(g) )^2, data = metsulfuron, 
           start = c(b1 = 138, b2 = 2470, b3 = 2, b4 = 0.07, g = log(0.3)),
