SUPPORT / SAMPLES & SAS NOTES
Problem Note 56676: PROC MODEL might terminate abnormally when the RESTRICT statement and the OPTIMIZE option in the SOLVE statement are specified
 |  |  |  |
PROC MODEL might generate error messages when all of the following conditions are met:
- Constraints are imposed by a RESTRICT statement.
- The OPTIMIZE option is specified in a SOLVE statement.
- The model equation contains the MOVEAVGn( x ) function.
Possible messages are:
ERROR: An exception has been encountered.
Please contact technical support and provide them with the following traceback information:
The SAS task name is [MODEL]
Exception occurred at (0C4A8C94)
Task Traceback
ERROR: Read Access Violation MODEL
If the expression in the RESTRICT statement can also be specified using the BOUNDS statement, then you can circumvent the problem by replacing the RESTRICT statement with the BOUNDS statement. If it is not possible to use a BOUNDS statement, the problem can be avoided by using the LAGn( < i,> x ) function or the ZLAGn( < i,> x ) function instead of the MOVAVGn( x ) function in the model equation.
For example, the MOVAVGn( x ) function is used in the model below:
data d;
y = 1;
do date = 1 to 5;
y = 0.9*y;
output;
end;
run;
proc model data=d;
endo y;
y = phi*movavg4(y);
solve phi / out=om;
quit;
The same model can be expressed using the ZLAGn( < i,> x ) as follows:
proc model data=d print;
endo y;
tot = 0;
cnt = min(_obs_-1,3);
do i = 1 to cnt;
tot = tot + zlag4(i,y);
end;
y = phi*1/(cnt+1)*(y + tot);
solve phi / out=ov;
quit;
