ICS_lcov: Local Shape Scatter Estimates for ICS

In ICSClust: Tandem Clustering with Invariant Coordinate Selection

Local Shape Scatter Estimates for ICS

Description

It is a wrapper for the local shape estimator of scatter as computed by fpc::localshape().

Usage

ICS_lcov(x, mscatter = "cov", proportion = 0.1, ...)

Arguments

x	a numeric matrix or data frame.
mscatter	"mcd" or "cov" (default); specified minimum covariance determinant or classical covariance matrix to be used for Mahalanobis distance computation.
proportion	proportion of points to be considered as neighbourhood.
...	potential further arguments passed to fpc::localshape().

Value

An object of class "ICS_scatter" with the following components:

location	this is NULL as the estimator does not use a location estimate.
scatter	a numeric matrix giving the estimate of the scatter matrix.
label	a character string providing a label for the scatter matrix.
