This instructs ASReml to obtain starting values from thesample covariance matrix of the data. For incomplete data the matrix so obtainedmay not, in general be positive definite. Care should be taken when using thisoption for incomplete multivariate data. The command to run !PATH 1 isasreml -nrw64 mt 1The Loglikelihood from this run is −20000 − 1444.93.
