  "Description": "Estimation and regularization for covariance matrix of\nasset returns. For covariance matrix estimation, three major\ntypes of factor models are included: macroeconomic factor\nmodel, fundamental factor model and statistical factor model.\nFor covariance matrix regularization, four regularized\nestimators are included: banding, tapering, hard-thresholding\nand soft- thresholding. The tuning parameters of these\nregularized estimators are selected via cross-validation.",
