MixSim : An R Package for Simulating Data to Study Performance of Clustering Algorithms

Blog Article

The R package MixSim is a new tool that allows simulating mixtures of Gaussian distributions with different levels of overlap between mixture components.Pairwise overlap, defined as a sum of two misclassification probabilities, measures the degree of interaction between components and can be readily employed to control the clustering complexity of datasets simulated from mixtures.These datasets can then be used for systematic performance investigation of clustering and finite mixture Goalie - Pants - Junior modeling algorithms.Among other capabilities Mirror Brackets and Accessories (Specific to Truck) of MixSim, there are computing the exact overlap for Gaussian mixtures, simulating Gaussian and non-Gaussian data, simulating outliers and noise variables, calculating various measures of agreement between two partitionings, and constructing parallel distribution plots for the graphical display of finite mixture models.All features of the package are illustrated in great detail.

The utility of the package is highlighted through a small comparison study of several popular clustering algorithms.
