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