Hi, I had a problem to get some of the values when I used 'systemfit()' function. I specified arguments of 'method (2SLS), eqns, eqnlables, inst, data' in 'systemfit()' function. And it failed to return the values such as 'residuals', 'x'(matrix of all regressors) etc as displayed on its reference manual page 23, 24. Is this because I didn't specify other arguments in 'systemfit()' function or other problems? Is there any other way to extract residuals, coefficients etc out of this simultaneous system after doing 'systemfit ()'? Thank you very much!!! Xia Feng
