Description Objects from the Class Slots Extends Methods Author(s) References See Also Examples
Holds the results of outlier identification using robust mahalanobis distances computed by robust multivarite location and covarince matrix.
Objects can be created by calls of the form new("OutlierMahdist", ...)
but the
usual way of creating OutlierMahdist
objects is a call to the function
OutlierMahdist()
which serves as a constructor.
covobj
:A list containing the robust estimates of multivariate location and covariance matrix for each class
call
:Object of class "language"
counts
:Number of observations in each class
grp
:Grouping variable
wt
:Weights
flag
:0/1 flags identifying the outliers
method
:Method used to compute the robust estimates of multivariate location and covariance matrix
singularity
:a list with singularity
information for the covariance matrix (or NULL
of not singular)
Class "Outlier"
, directly.
Return the cutoff value used to identify outliers
Return a vector containing the computed distances
