In cosso: Fit Regularized Nonparametric Regression Models Using COSSO Penalty

Plot method for COSSO object

Description

Plot L_2 norm solution path or main effects of selected functional components

Usage

## S3 method for class 'cosso'
plot(x,M,plottype =c("Path","Functionals"),eps=1e-7,...)

Arguments

x	a cosso object.
M	a smoothing parameter value. Argument required when plottype="Functionals".
plottype	either Path (default) or Functionals. The Path plot shows the L_2 norm path for each functional component as a function of smoothing parameter M. The Functional plot shows the estimated functional components for each input variable at a particular smoothing parameter M. Abbreviations are allowed.
eps	an effective zero, default is 1e-7.
...	additional arguments for plot generic.

Value

NULL

Examples

set.seed(20130310)
x=cbind(rbinom(200,1,.7),matrix(runif(200*7,0,1),nc=7))
trueProb=1/(1+exp(-x[,1]-sin(2*pi*x[,2])-5*(x[,4]-0.4)^2))
y=rbinom(200,1,trueProb)

B.Obj=cosso(x,y,family="Bin")
plot.cosso(B.Obj,plottype="Path")
plot.cosso(B.Obj,M=2,plottype="Func")
