Proc Mixed Predictions

[xtc283x]

In producing predicted output from Proc Mixed using the Model statement, are the predictions for the fixed effects only? If so, how does one update the predictions to include the additional variance explained by using the Random or Repeated statements?

The OUTM= option on the model statement gives you just the predicted fixed-effects means (and associated statistics, such as standard errors). The OUTP= option gives you the predictions for fixed and random effects (i.e., the EBLUPS), with associated statistics.
