How to prepare a NULL model without getting the HESSIAN error in the output?

10 October 2016 1 9K Report

I am able to get the estimated model along with the constant only model, but unable to get the null model without the hessian error. Along with the error I am getting the null log likelihood, through which I am able to calculate the rho square with respect to null model. But, that hessian error is still there. Apart from that, I have used ;asc for getting ASC only model but getting error 1024 and error 1049. Kindly provide some useful information.
