PlotAdaptiveReg: Eigenvectors - R^2 plot

In fhebert/AdaptivePrediction: Adaptive Prediction Rules

Description

This function produces a plot of the R^2 estimated by cross-validation as a function of the number of eigenvectors included in the fitting. The vertical red lines indicated the optimal R^2 and the corresponding number of eigenvectors.

Usage

PlotAdaptiveReg(fit)

Arguments

fit	An object containing a fitted model obtained by the AdaptiveReg function.

Examples

library(prospectr)
data(NIRsoil)
indNA = which(is.na(NIRsoil$Nt))
NIRNt = list(x=NIRsoil$spc[-indNA,],y=NIRsoil$Nt[-indNA])
fit = AdaptiveReg(NIRNt$x,NIRNt$y,nvmax=100)
PlotAdaptiveReg(fit)
