PROC MIXED Options
Use this parameter to select any options to be added to the PROC MIXED statement.
Available options are listed in the following table:
Displays asymptotic correlation matrix of covariance parameter estimates. It is computed from the corresponding asymptotic covariance matrix. (See the description of the ASYCOV option, below.)
Displays asymptotic standard errors and Wald tests for covariance parameters .
Computes the estimated variance-covariance matrix of the fixed-effects parameters by using the asymptotically consistent (or sandwich) estimator.
Displays additional tables of model, dimensional and other information.
Note: This option was designed for use with analyses requiring extensive CPU resources.
When you select this option, an analysis of variance table is included in the output, and the expected mean squares are used to estimate the variance components see The GLM Procedure for further explanation). The resulting method-of-moment variance component estimates are used in subsequent calculations, including Type 1 standard errors computed from ESTIMATE and LSMEANS statements.
Note: This option applies only to variance component models with no SUBJECT= effects and no REPEATED statement.
When you select this option, an analysis of variance table is included in the output, and the expected mean squares are used to estimate the variance components. (See The GLM Procedure for further explanation.) The resulting method-of-moment variance component estimates are used in subsequent calculations, including Type 2 standard errors computed from ESTIMATE and LSMEANS statements.
Note: This option applies only to variance component models with no SUBJECT= effects and no REPEATED statement.
When you select this option, an analysis of variance table is included in the output, and the expected mean squares are used to estimate the variance components. (See The GLM Procedure for further explanation.) The resulting method-of-moment variance component estimates are used in subsequent calculations, including Type 3 standard errors computed from ESTIMATE and LSMEANS statements.
Note: This option applies only to variance component models with no SUBJECT= effects and no REPEATED statement.

Suppresses the display of the Class Level Information table if you do not specify number.
Suppresses the display of the Iteration History table.
Displays ordinates of the relevant distribution in addition to p-values. The ordinate can be viewed as an approximate odds ratio of hypothesis probabilities.
