Non-Gaussian Mixture Model Averaging for Clustering

The Gaussian mixture model has been used for model-based clustering analysis for
decades. Most model-based clustering analyses are based on the Gaussian mixture
model. Model averaging approaches for Gaussian mixture models are proposed by
Wei and McNicholas, based on a family of 14 Gaussian parsimonious clustering
models. In this thesis, we use non-Gaussian mixture
models, namely the tEigen family, for our averaging approaches. This paper studies
fitting in an averaged model from a set of multivariate t-mixture models instead of
fitting a best model. / Thesis / Master of Science (MSc)
