Random Statement Options

Use this field to specify options to be included in the RANDOM statement.

Specified options are included in the MIXED procedure RANDOM statement for continuous traits.

If the Type of Tests to Perform is Binary, Nominal, or Ordinal, specified options are included in the GLIMMIX procedure RANDOM statement in the Random Statement Options field.

You can specify any RANDOM Statement option using the following syntax:

Option

where:

•

OPTION is the Random Statement option, and

•

a space is used to delimit individual conditions.

Examples of commonly used PROC GENESELECT options are listed in the following table.

Option	Definition
CL	Requests confidence limits for predictors of random effects. The confidence level is 0.95 by default; this can be changed using the Adjustment Effects parameter.
SUBJECT=	Identifies the subjects in the model. Complete independence is assumed across subjects. Specifying a subject effect is equivalent to nesting all other effects in the RANDOM statement within the subject effect.
GROUP=	Varies covariance parameters by groups. Each new level of the grouping effect produces a new set of covariance parameters. Continuous variables and computed variables are permitted as group effects.
