Dear All, I am estimating a system of 4 nonlinear equations with the command nlsur. I have the following problems: 1) The R-squared of two equations is negative 2) Using the fgnls option the standard error of some parameter estimate is missing My variables do not have any missing value and I do not have any dummy.
