  "Description": "Solves multivariate least squares (MLS) problems subject\nto constraints on the coefficients, e.g., non-negativity,\northogonality, equality, inequality, monotonicity, unimodality,\nsmoothness, etc. Includes flexible functions for solving MLS\nproblems subject to user-specified equality and/or inequality\nconstraints, as well as a wrapper function that implements 24\ncommon constraint options. Also does k-fold or generalized\ncross-validation to tune constraint options for MLS problems.\nSee ten Berge (1993, ISBN:9789066950832) for an overview of MLS\nproblems, and see Goldfarb and Idnani (1983)\n<doi:10.1007/BF02591962> for a discussion of the underlying\nquadratic programming algorithm.",
