Mixtures of Multiple Scaled Student T distributions

Keywords: Medical imaging - Brain MRI - Statistics - Health - Robust clustering

Functional Description: The package implements mixtures of so-called multiple scaled Student distributions, which are generalisation of multivariate Student T distribution allowing different tails in each dimension. Typical applications include Robust clustering to analyse data with possible outliers. In this context, the model and package have been used on large data sets of brain MRI to segment and identify brain tumors.
