PRINT Subcommand (VARCOMP command)

The PRINT subcommand controls the display of optional output. If PRINT is not specified, the default output includes a factor information table and a variance component estimates table.

• For the maximum likelihood (ML) and restricted maximum likelihood (REML) methods, an asymptotic covariance matrix of the variance estimates table is also displayed.
• If more than one PRINT subcommand is specified, the specifications are accumulated. However, if you specify the keyword HISTORY more than once but with different values for n, the last specification is in effect.

EMS. Expected mean squares. This output shows expected mean squares of all of the effects. This process is available only if you specify SSTYPE(n) on the METHOD subcommand.

HISTORY(n). Iteration history. The table contains the objective function value and variance component estimates at every n iteration. The value for n must be a positive integer. The default is 1. The last iteration is always printed if HISTORY is specified on PRINT. This process is available only if you specify ML or REML on the METHOD subcommand.

SS. Sums of squares. The table contains sums of squares, degrees of freedom, and mean squares for each source of variation. This process is available only if you specify SSTYPE(n) on the METHOD subcommand.
