Hello!
I am trying to estimate a Linear expenditure system with the nlsur command. I want to have a constraint on the beta-parameters so the sum to 1. With 2 parameters I do it like on the picture but I don't know how to do it when I add another equation Y4 that will estimate b2, b3 and b4 with the constraint: b2+b3+b4 = 1
With two parameters I do like this:
Thank you in advance!
