  <dc:title>Constrained Multivariate Least Squares</dc:title>
  <dc:title>R package CMLS version 1.1</dc:title>
  <dc:description>Solves multivariate least squares (MLS) problems subject to constraints on the coefficients, e.g., non-negativity, orthogonality, equality, inequality, monotonicity, unimodality, smoothness, etc. Includes flexible functions for solving MLS problems subject to user-specified equality and/or inequality constraints, as well as a wrapper function that implements 24 common constraint options. Also does k-fold or generalized cross-validation to tune constraint options for MLS problems. See ten Berge (1993, ISBN:9789066950832) for an overview of MLS problems, and see Goldfarb and Idnani (1983) &lt;doi:10.1007/BF02591962&gt; for a discussion of the underlying quadratic programming algorithm.</dc:description>
