The SYSLIN Procedure |

**OUTPUT****PREDICTED***=variable*RESIDUAL*=variable*;

The OUTPUT statement writes predicted values and residuals from the preceding model to the data set specified by the OUT= option on the PROC SYSLIN statement. An OUTPUT statement must come after the MODEL statement to which it applies. The OUT= option must be specified in the PROC SYSLIN statement.

The following options can be specified in the OUTPUT statement:

**PREDICTED=***variable*- names a new variable to contain the predicted values for the response variable. The PREDICTED= option can be abbreviated as PREDICT=, PRED=, or P=.
**RESIDUAL=***variable*-
names a new variable to contain the residual values for the
response variable.
The RESIDUAL= option can be abbreviated as RESID= or R=.
For example, the following statements create an output data set named B.
In addition to the variables in the input data set,
the data set B contains the variable YHAT, with values that are predicted
values of the response variable Y,
and YRESID, with values that are the residual values of Y.
proc syslin data=a out=b; model y = x1 x2; output p=yhat r=yresid; run;

For example, the following statements create an output data set named PRED. In addition to the variables in the input data set, the data set PRED contains the variables Q_DEMAND and Q_SUPPLY, with values that are predicted values of the response variable Q for the demand and supply equations respectively, and R_DEMAND and R_SUPPLY, with values that are the residual values of the demand and supply equations.proc syslin data=in out=pred; demand: model q = p y s; output p=q_demand r=r_demand; supply: model q = p u; output p=q_supply r=r_supply; run;

See the section "OUT= Data Set" later in this chapter for more details.
