HDclassif-package: High Dimensional Discriminant Analysis and Data Clustering

Description

Disciminant analysis and data clustering methods for high dimensional data, based on the asumption that high-dimensional data live in different subspaces with low dimensionality, proposing a new parametrization of the Gaussian mixture model which combines the ideas of dimension reduction and constraints on the model.

This package is used to make efficient supervised and unsupervised classification with high dimensional data. The supervised method uses the hdda function to get the data parameters and the predict function to realise the class prediction of a dataset. The unsupervised method is implemented in the hddc function, and once the parameters are estimated, the predict gives the class prediction of other datasets. The method used in the hddc is based on the Expectation - Maximisation algorithm.
