I am fittting a linner regression with constrained parameters, saying, all parameters are non-negative and sum up to 1.
I have searched historical R-help and found that this can be done by solve.QP from the quadprog package. I need to assess the significance of the coefficient estimates, but there is no standard error of the coefficient estimates in the output. So I can not compute the p-value. Is there any other methods or packages which can do the constained regression with the standard error or p-values in the output? Thanks!
