Description: Estimation of robust estimators for multi-group and
        spatial data including the casewise robust Spatially Smoothed
        Minimum Regularized Determinant (ssMRCD) estimator and its
        usage for local outlier detection as described in Puchhammer
        and Filzmoser (2023) <doi:10.1080/10618600.2023.2277875> as
        well as for sparse robust PCA for multi-source data described
        in Puchhammer, Wilms and Filzmoser (2024)
        <doi:10.48550/arXiv.2407.16299>. Moreover, a cellwise robust
        multi-group Gaussian mixture model (MG-GMM) is implemented as
        described in Puchhammer, Wilms and Filzmoser (2024)
        <doi:10.48550/arXiv.2504.02547>. Included are also
        complementary visualization and parameter tuning tools.
