covfmDistance2Plot {robust} | R Documentation |
Given a fit.models object containing two elements of either class "cov" or "covRob", plots the square root of the Mahalanobis distances from the first element on the y-axis and the square root of the Mahalanobis distances from the second element on the x-axis. A 45 degree line is drawn as well.
covfmDistance2Plot(x, chisq.percent = 0.975, id.n = 3, ...)
x |
an object of class "covfm" containing 2 elements. |
chisq.percent |
a numeric value between 0 and 1 giving the chi-squared percent point used to compute the outlyingness threshold. |
id.n |
a positive integer specifying the number of extreme points to label in the plot. |
... |
additional arguments are passed to the low-level plotting functions. |
This function is called by the generic function plot.covfm
.
x is invisibly returned.
