  "Description": "Provides tools for factor analysis in high-dimensional\nsettings under copula-based factor models. It includes\nfunctions to simulate factor-model data with copula-distributed\nidiosyncratic errors (e.g., Clayton, Gumbel, Frank, Student t\nand Gaussian copulas) and to perform diagnostic tests such as\nthe Kaiser-Meyer-Olkin measure and Bartlett's test of\nsphericity. Estimation routines include principal component\nbased factor analysis, projected principal component analysis,\nand principal orthogonal complement thresholding for large\ncovariance matrix estimation. The philosophy of the package is\ndescribed in Guo G. (2023) <doi:10.1007/s00180-022-01270-z>.",
