PREDICT Statement

The NLMIXED Procedure

PREDICT Statement

PREDICT expression OUT=SAS-data-set ;

The PREDICT statement enables you to construct predictions of an expression across all of the observations in the input data set. Any valid SAS programming expression involving the input data set variables, parameters, and random effects is valid. Predicted values are computed using the parameter estimates and empirical Bayes estimates of the random effects. Standard errors of prediction are computed using the delta method (Billingsley 1986). Results are placed in an output data set that you specify with the OUT= option. Additional computed quantities can be added to this data set with the ID statement.

The following options are available in the PREDICT statement:

ALPHA= $\alpha$: specifies the alpha level to be used in computing t statistics and intervals. The default value corresponds to the ALPHA= option in the PROC NLMIXED statement.
DF=d: specifies the degrees of freedom to be used in computing t statistics and intervals in the OUT= data set. The default value corresponds to the DF= option in the PROC NLMIXED statement.
