  "Description": "Constrained ordinary least squares is performed. One\nconstraint is that all beta coefficients (including the\nconstant) cannot be negative. They can be either 0 or strictly\npositive. Another constraint is that the sum of the beta\ncoefficients equals a constant. References: Hansen, B. E.\n(2022).
