VARCOMP

VARCOMP is available in Custom Tables and Advanced Statistics.

The VARCOMP procedure estimates variance components for mixed models.

VARCOMP dependent variable BY factor list [WITH covariate list] 

  /RANDOM = factor [factor ...]

 [/METHOD = {MINQUE({1})**}]
                    {0}
            {ML           }
            {REML         }
            {SSTYPE({3})  }
                    {1}

 [/INTERCEPT = {INCLUDE**}]
               {EXCLUDE    }

 [/MISSING = {EXCLUDE**}]
             {INCLUDE  }

 [/REGWGT = varname]

 [/CRITERIA = [CONVERGE({1.0E-8**})] [EPS({1.0E-8**})] [ITERATE({50**})]]
                        {n       }        {n       }            {n   }

 [/PRINT = [EMS] [HISTORY({1**})] [SS]]
                          {n  }

 [/OUTFILE = [VAREST] [{COVB}] ('savfile'|'dataset') ]
                       {CORB}

 [/DESIGN = {[INTERCEPT] [effect effect ...]}]

** Default if the subcommand or keyword is omitted.

This command reads the active dataset and causes execution of any pending commands. See the topic Command Order for more information.

Syntax for the VARCOMP command can be generated from the Variance Components Analysis dialog.

Example

VARCOMP Y1 BY B C WITH X1 X2
 /RANDOM = C.
