Beta.m                  A simulated Beta matrix
Cal_grpWTs              An auxilary function calculating the group
                        weighting matrix 'grpWTs' required when calling
                        the MSGlasso function.
FindingGRGrps           An auxilary function calculating the containing
                        variable index for each predictor (or response)
                        group. It generates the required input
                        'GR.grps' matrix when calling the MSGlasso
                        function.
FindingPQGrps           An auxilary function calculating the group
                        attribution index for each predictor (or
                        response) variable. It generates the required
                        input 'PQ.grps' matrix when calling the
                        MSGlasso function.
MSGLasso                A function to fit the Multivariate Sparse Group
                        Lasso with an arbitrary group structure
                        (MSGLasso)
MSGLasso.cv             Fit the MSGLasso for a series sets of tuning
                        parameters and use the k-fold cross validation
                        to select the optimal tunning parameter set.
