OUTFILE Subcommand (VARCOMP command)

The OUTFILE subcommand writes the variance component estimates to a data file or a previously declared dataset (DATASET DECLARE command) that can be used in other procedures. For the ML and REML methods, OUTFILE can also write the asymptotic covariance or correlation matrix. If more than one OUTFILE subcommand is specified, the last specification is in effect.

• OUTFILE writes to an external data file or previously declared dataset. You must specify a quoted file specification or dataset name in parentheses.
• COVB and CORB are available only if you specify ML or REML on the METHOD subcommand.
• COVB and CORB are mutually exclusive; only one of them can be specified on an OUTFILE subcommand.

VAREST. Variance component estimates. A variable will be created to contain the estimates, and another variable will be created to hold the labels of the variance components.

COVB. Covariance matrix. This matrix is the asymptotic covariance matrix of the variance component estimates. One variable is created for each variance component.

CORB. Correlation matrix. This matrix is the asymptotic correlation matrix of the variance component estimates. One variable is created for each variance component.

('savfile'|'dataset'). Output file specification or previously declared dataset name. Specify a quoted file specification or dataset name, enclosed in parentheses. The variance component estimates and the asymptotic covariance or correlation matrix (if requested) are written to the same file.
