mht (version 3.1.2)

plot: graphical output for a mht or mht.order object

Description

Graphical output for a mht or mht.order object. Four plots (selectable by which.plot) are currently available: a plot of the fitted values against the true values, a plot of the residuals against the fitted values, a Normal Q-Q plot, and a barplot showing the coefficients.

Usage

"plot"(x,which.plot=1:4,...)
"plot"(x,which.plot=1:4,...)

Arguments

x

Object of class "mht" as obtained from mht or "mht.order" as obtained from mht.order.

which.plot

if a subset of the plots is required, specify a subset of the numbers 1:4.

...

not used.

Details

The four plots are shown for each level alpha of the mht or mht.order object.

For the Normal Q-Q plot, the standardized residuals are used. They are calculated as R[i]/sqrt(var(R)).

Examples

## Not run: 
# x=matrix(rnorm(100*20),100,20)
# beta=c(rep(2,5),rep(0,15))
# y=x%*%beta+rnorm(100)
# 
# # mht
# mod=mht(x,y,alpha=c(0.1,0.05),maxordre=15)
# plot(mod)
# 
# # mht.order
# mod.order=mht.order(x,y,ordre=5:1,alpha=c(0.1,0.05))
# plot(mod.order)
