Description: Computing elliptical joint confidence regions at a
        specified confidence level. It provides the flexibility to
        estimate either classical or robust confidence regions, which
        can be visualized in 2D or 3D plots. The classical approach
        assumes normality and uses the mean and covariance matrix to
        define the confidence regions. Alternatively, the robustified
        version employs estimators like minimum covariance determinant
        (MCD) and M-estimator, making them less sensitive to outliers
        and departures from normality. Furthermore, the functions allow
        users to group the dataset based on categorical variables and
        estimate separate confidence regions for each group. This
        capability is particularly useful for exploring potential
        differences or similarities across subgroups within a dataset.
