plot.edr {EDR}R Documentation

Plot results produced by function edr.

Description

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

Usage

plot.edr(x, m = 1, ylab = "Y", title = "", sm = require(sm), ...)

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 or require(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}.
