In NumbersInternational/qrserver: R Analysis Functions for Q

Description

reports the goodness-of-fit of an object.

Usage

GoodnessOfFitPlot(object, ...)

## Default S3 method:
GoodnessOfFitPlot(object, digits = max(3L,
  getOption("digits") - 3L), ...)

## S3 method for class 'lm'
GoodnessOfFitPlot(object, digits = max(3L, getOption("digits") -
  3L), ...)

## S3 method for class 'smacof'
GoodnessOfFitPlot(object, ...)

## S3 method for class 'smacofR'
GoodnessOfFitPlot(object, ...)

Arguments

object	An object for which a summary is desired.
...	Additional arguments affecting the goodness-of-fit displayed.
digits	Minimal number of significant digits, see print.default.

Methods (by class)

• default: Default goodness-of-fit plot

• lm: Goodness-of-fit plot for a linear model

• smacof: Goodness-of-fit plot for a square smacof object

• smacofR: Goodness-of-fit plot for a rectangular smacof object

Examples

# linear regression
x <- rnorm(10)
y <- rnorm(10) + x
mod <- lm(y ~ x)
GoodnessOfFitPlot(mod)

# MDS - square
library(smacof)
data(breakfastDissimilarities)
mdsInterval <- smacofSym(breakfastDissimilarities[[4]],
    type = "interval", eps = 1e-12, itmax = 100000)
GoodnessOfFitPlot(mdsInterval)
