Outlier-class: Class "Outlier" -- a base class for outlier identification

Description

The class Outlier represents the results of outlier identification.

Arguments

Objects from the Class

A virtual Class: No objects may be created from it.

Slots

call:

Object of class "language"

counts:

Number of observations in each class

grp:

Grouping variable

wt:

Vector of weights

flag:

0/1 flags identifying the outliers

method:

A character string specifying the method used to identify the outliers. In case of '>OutlierMahdist class this is the name of the robust estimator of multivariate location and covariance matrix used

singularity:

a list with singularity information for the covariance matrix (or NULL if not singular)

Methods
