EViews.com

I am trying to estimate a parity bound model. I got the code for the programme from a earlier post. But when I run the programme, eviews give a warning msg, which says. " singular covariance- coefficients are not unique. further it does not give values for std.error, z-statistic or prob.

Any help in this is greatly appreciated.

Try different starting values. Sometimes that helps, but not always.
