%description
Enables the generation of Laplace factor models across diverse Laplace
distributions and facilitates the application of Sparse Online Principal
Component (SOPC), Incremental Principal Component (IPC), Parallel
Principal Component (PPC), Sparse Approximate Principal Component (SAPC),
Standard Principal Component (SPC), and Farm Test methods to these models.
Evaluates the efficacy of these methods within the context of Laplace
factor models by scrutinizing parameter estimation accuracy, mean square
error, and the degree of sparsity.
