%description
Generates Skew Factor Models data and applies Sparse Online Principal
Component (SOPC), Incremental Principal Component (IPC), Projected
Principal Component (PPC), Perturbation Principal Component (PPC),
Stochastic Approximation Principal Component (SAPC), Sparse Principal
Component (SPC) and other PC methods to estimate model parameters. It
includes capabilities for calculating mean squared error, relative error,
and sparsity of the loading matrix.The philosophy of the package is
described in Guo G. (2023) <doi:10.1007/s00180-022-01270-z>.
