plot.xdistResscale: Illustrate Completeness Test for Regression Model

In regr0: Building regression models

Description

Plots mean absolute differences of residuals against mean x-distance of pairs of observations, classified on the basis of their x-distance. The distance is proportional to the Mahalanobis distance in the design space.

Usage

## S3 method for class 'xdistResscale'
plot(x, lwd=2, cex=2, xlab = "distance in x space",
  ylab = "average abs. residual difference", col.aux = "grey30", ...)

Arguments

x	an object of class xdistResscale
lwd, cex	line width and character expansion for plotting
xlab, ylab	label for axes
col.aux	color to be used for auxiliary lines
...	arguments passed to plot.default

Value

none.

Examples

data(d.blast)
rr <- regr(tremor~distance+charge, data=d.blast)
## an inadequate model!
xdrd <- xdistResdiff(rr)
plot(xdrd)
