EDR (version 0.6-6)

plot.edr: Plot results produced by function edr.

Description

Illustrate the fitted model within the estimated one or two-dimensional effective dimension reduction (EDR) space.

Usage

# S3 method for edr
plot(x, m = 1, ylab = "Y", title = "", sm = TRUE, ...)

Arguments

x

Object of class "edr".

m

Dimension of the effective dimension reduction (EDR) space. m=1 corresponds to single index models, m>1 specifies a multiindex model. Values of m>2 are currently not allowed.

ylab

Label for the response variable.

title

Optional title.

sm

If sm==TRUE nonparametric regression is performed within the m-dimensional EDR using function sm.regression from package sm. If sm==FALSE oversmoothed fitted values calculated within function edr are used for visualisation.

...

Additional parameters will be passed to plot in case of m=1 and to image if m=2.

Value

Returns invisible{NULL}.
