Thanks guys (and girls),

Here are the notes from my SAS Log on Proc Mixed.
NOTE: 6 observations are not included because of missing values.
NOTE: Convergence criteria met but final hessian is not positive definite.
NOTE: Asymptotic variance matrix of covariance parameter estimates has been found to be singular and a generalized inverse was used. Covariance parameters with zero variance do not contribute to degrees of freedom computed by DDFM=SATTERTH.


I think this is problematic... One runs a dataset and SCABE criteria for Swr not met so he/she resorts to the ABE routine. Tada!

Thanks
John
