In MSclust: Multiple-Scaled Clustering

A Mixture of Two Normal Distributions with outliers

Description

A simulated mixture of two normal distributions with mean (0,0) and (2,4), respectively, the fist covariance matrix has diagonlas equal to 2 and covariance 1.5, the second 0.5 and 0.1 respectively. Moreover, 18 observations have been transformed in outliers. For details, see Punzo, A. & Tortora, C. (2021). Multiple scaled contaminated normal distribution and its application in clustering. Statistical Modelling, 21(4): 332–358.

Usage
