gof {spaMM}R Documentation

Goodness of fit test

Description

Performs a test of goodness of fit. The only method implemented so far is based on randomized quantile residuals (Dunn & Smyth, 1996).

Usage

gof(object, method = "RQR", ...)

Arguments

object

A fit object inheriting from class "HLfit", as returned by spaMM's main fitting functions.

method

Character string; a method of test of goodness of fit.

...

Further arguments possibly passed to internal methods.

Value

Returns the value of a call to shapiro.test (“a list with class "htest"”) with added element RQR, itself a list including the randomized residuals.

Examples

data("Orthodont", package = "nlme")
sp1 <- fitme(distance ~ age * Sex + (1 | Subject), data = Orthodont)
gof(sp1) #  classic toy example, but poor fit.
