%description
Provides a distributed framework for simulating and estimating skew factor
models under various skewed and heavy-tailed distributions. The methods
support distributed data generation, aggregation of local estimators, and
evaluation of estimation performance via mean squared error, relative
error, and sparsity measures. The distributed principal component (PC)
estimators implemented in the package include 'IPC' (Independent Principal
Component),'PPC' (Project Principal Component), 'SPC' (Sparse Principal
Component), and other related distributed PC methods. The methodological
background follows Guo G. (2023) <doi:10.1007/s00180-022-01270-z>.
