Plot a MSPE or MAPE object

Description

The function plot.MSPE plots a MSPE object that is returned by the MSPE function. The function plot.MAPE plots a MAPE object that is returned by the MAPE function.

Usage

## S3 method for class 'MSPE'
plot(x, vr = NULL, h = 1, N_min = 1, legend = TRUE,
  display.mins = TRUE, add.for.legend = 0, ...)

## S3 method for class 'MAPE'
plot(x, vr = NULL, h = 1, N_min = 1, legend = TRUE,
  display.mins = TRUE, add.for.legend = 0, ...)

Arguments

x

The MSPE or MAPE object to be plotted.

vr

parameter to plot a line at level vr. Intended to be used to plot the mean squared prediction error of the trivial, null predictor; optional.

h

Defines for which h-step predictor the mean squared prediction errors will be shown; default: 1.

N_min

If specified, the mean squared prediction errors with N < N_{\rm min} will not be shown; integer and optional.

legend

Flag to specify if a legend, indicating which colour of the lines corresponds to which p, will be shown; default: TRUE.

display.mins

Flag to specify if the minima for each p, and the minimum accross N=0 will be highlighted.

add.for.legend

add this much extra space for the legend, right of the lines.

...
