Abstract: | This paper proposes a new way of overcoming the existing
limitations. It generalizes the model used in the previous approaches by
introducing a more comprehensive portfolio of covariance matrix structures.
Further, this paper proposes a Bayesian solution in the presence of the noise
in clustering problems. The performace of the proposed method is first studied
by simulation; the procedure is also applied to the analysis of data
concerning species of butterflies and diabetes patients. |
