The Hessian is the matrix of second derivatives of the objective function you are attempting to minimize (resp. maximize, depending on how SAS set this up). The Hessian is a square k × k matrix, where k is the number of parameters in your model. In your case, the Hessian is singular, which means that your parameters are …
