Model Based Clustering

Description

Calls Model based clustering of [Fraley/Raftery, 2006] which models a Mixture Of Gaussians (MoG).

Usage

ModelBasedClustering(Data,ClusterNo=2,PlotIt=FALSE,...)

Arguments

Data	[1:n,1:d] matrix of dataset to be clustered. It consists of n cases of d-dimensional data points. Every case has d attributes, variables or features.
ClusterNo	A number k which defines k different clusters to be built by the algorithm.
PlotIt	Default: FALSE, If TRUE plots the first three dimensions of the dataset with colored three-dimensional data points defined by the clustering stored in Cls
...	Further arguments to be set for the clustering algorithm, if not set, default arguments are used.

Details

see [Thrun, 2017, p. 23] or [Fraley/Raftery, 2002] and [Fraley/Raftery, 2006].

Value

List of

Cls	[1:n] numerical vector with n numbers defining the classification as the main output of the clustering algorithm. It has k unique numbers representing the arbitrary labels of the clustering.
Object	Object defined by clustering algorithm as the other output of this algorithm

Note

MoGclustering used in [Thrun, 2017] was renamed to ModelBasedClustering in this package.
