The "Stop Reason" table displays the reason why the selection stopped. To facilitate programmatic use of this table, an integer code is assigned to each reason and is included if you output this table by using an ODS OUTPUT statement. The reasons and their associated codes follow:
Code |
Stop Reason |
---|---|
1 |
All eligible effects are in the model. |
2 |
All eligible effects have been removed. |
3 |
Specified maximum number of steps have been done. |
4 |
The model contains the specified maximum number of effects. |
5 |
The model contains the specified minimum number of effects (for backward selection). |
6 |
The stopping criterion is at a local optimum. |
7 |
No suitable add or drop candidate could be found. |
8 |
Adding or dropping any effect does not improve the selection criterion. |
9 |
No candidate meets the appropriate SLE or SLS significance level. |
10 |
Stepwise selection is cycling. |
11 |
The model is an exact fit. |
12 |
Dropping an effect would result in an empty model. |
You can suppress the "Stop Reason" table by specifying DETAILS=NONE in the SELECTION statement.
