Constrained regression
Dear list members,
I am trying to get information on how to fit a linear regression with
constrained parameters. Specifically, I have 8 predictors , their
coeffiecients should all be non-negative and add up to 1. I understand it is
a quadratic programming problem but I have no experience in the subject. I
searched the archives but the results were inconclusive.
Could someone provide suggestions
