Axis-parallel subspace clustering algorithms
The clustering algorithms in this package are instances of both, projected clustering algorithms or
subspace clustering algorithms according to the classical but somewhat obsolete classification schema
of clustering algorithms for axis-parallel subspaces.

P3C.findOutliers(Relation<V> relation,
List<MultivariateGaussianModel> models,
ArrayList<P3C.ClusterCandidate> clusterCandidates,

point in a cluster against the critical value of the ChiSquared
distribution with as many degrees of freedom as the cluster has relevant
attributes.
