Re: Putting limits on estimated coefficient values

Hi everyone, I’m going to estimate a system of LES demand equations by applying Seemingly Unrelated Regression (SURE) method. For this purpose, one of the coefficients must be positive. To explain clearly, this is my demand function: Pi*Xi = Pi*μi + αi(m-∑Pj*μj) In which, μ>0 and ∑αi =1 must be impo...
