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.

## S3 method for class 'mht'
plot(x,which.plot=1:4,...)
## S3 method for class 'mht.order'
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)).
