%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.
