lmfmSqrtResVsFittedPlot: Square Root of Absolute Residuals vs. Fitted Values Plot

Description

Produces a side-by-side plot of the square root of the absolute values of the residuals versus the fitted values.

Usage

lmfmSqrtResVsFittedPlot(x, type = "response", smooths = FALSE, rugplot = FALSE, id.n = 3, ...)

Arguments

x

an lmfm object.

type

a character string specifying the type of residuals used in the plot. This argument is passed to the generic residuals function when extracting the residuals from x.

smooths

a logical value. If TRUE then a smooth curve computed using loess is included in each panel of the plot.

rugplot

a logical value. If TRUE then a rugplot is included in each panel of the plot.

id.n

a non-negative integer value giving the number of extreme points to identify.

...

any additional arguments are passed to xyplot.

Value

• the trellis object is invisibly returned.
