The SIMLIN Procedure |

**PROC SIMLIN***options;*

**DATA=***SAS-data-set*-
specifies the SAS data set containing input data for the simulation.
If the DATA= option is used, the data set specified
must supply values for all exogenous variables
throughout the simulation.
If the DATA= option is not specified,
no simulation of the system is performed, and
only the reduced form and multipliers are computed.
**EST=***SAS-data-set*-
specifies the input data set containing the structural coefficients of the system.
If EST= is omitted the most recently created SAS data set is used.
The EST= data set is normally a "TYPE=EST" data set produced
by the OUTEST= option of PROC SYSLIN.
However, you can also build the EST= data set with a SAS DATA step.
See "The EST= Data Set" later in this chapter for details.
**ESTPRINT**-
prints the structural coefficients read from the EST= data set.
**INTERIM=***n*-
rssbjixinterim multipliersSIMLIN procedure
equests that interim multipliers be computed for interims 1 through
*n*. If not specified, no interim multipliers are computed. This feature is available only if there are no lags greater than 1. **NOPRINT**-
suppresses all printed output.
**NORED**-
suppresses the printing of the reduced form coefficients.
**OUTEST=***SAS-data-set*-
specifies an output SAS data set to contain the
reduced form coefficients and multipliers,
in addition to the structural coefficients read from the EST= data set.
The OUTEST= data set has the same form as the EST= data set.
If the OUTEST= option is not specified, the reduced form coefficients
and multipliers are not written to a data set.
**START=***n*-
specifies the observation number in the DATA= data set where the
dynamic simulation is to be started.
By default, the dynamic simulation starts with the first observation
in the DATA= data set for which all variables (including lags)
are not missing.
**TOTAL**-
requests that the total multipliers be computed.
This feature is available only if there are no lags greater than 1.
**TYPE=***value*-
specifies the type of estimates to be read from the EST= data set.
The TYPE= value must match the value of the _TYPE_ variable
for the observations that you want to select
from the EST= data set (TYPE=2SLS, for example).
