  "Description": "The elliptical factor model, as an extension of the\ntraditional factor model, effectively overcomes the limitations\nof the traditional model when dealing with heavy-tailed\ncharacteristic data. This package implements sparse principal\ncomponent methods (SPC) and bi-sparse online principal\ncomponent estimation (SPOC) for parameter estimation. Includes\nfunctionality for calculating mean squared error, relative\nerror, and loading matrix sparsity.The philosophy of the\npackage is described in Guo G. (2023)\n<doi:10.1007/s00180-022-01270-z>.",
