Implements a robust covariance estimator: Rousseeuw's MCD.
...
Minimum Covariance Determinant (MCD) is a robust estimator of
covariance introduced by Rousseeuw [1]. The main idea behind the MCD
is to find a fixed proportion of observations whose scatter matrix has
the minimum determinant.
The MCD estimator is computed with the FastMCD algorithm [2].

Large size work better because they give a better training set to the
