%description
Generates Skew Factor Models data and applies Sparse Online Principal
Component (SOPC) method to estimate model parameters. It includes
capabilities for calculating mean squared error, relative error, and
sparsity of the loading matrix. Additionally, it includes robust
regression methods such as adaptive Huber regression.The philosophy of the
package is described in Guo G. (2023) <doi:10.1007/s00180-022-01270-z>.
