At convergence, the coefficients are the solutions to equations of the form (X'WX)**-1X'WY, so one might consider looking at the transformed variables Z=W**(1/2)Y and U=W**(1/2)X and carrying out the same analysis that you did for linear regression. I believe the analogy carries through exactly. Tony Lachenbruch
