Problem Note 45819: Constrained Optimal binning results might be incorrect in the Interactive Grouping node and a "Monotonicity is infeasible.." warning appears
 |  |  |  |  |
The Interactive Grouping node in SAS® Enterprise Miner™ enables you to specify grouping methods for interval and for ordinal variables. However, the results might be incorrect if both of the following conditions are true:
- Interval Grouping Method or Ordinal Grouping Method is Constrained Optimal
- Apply WOE Monotonicity is Yes
To determine whether the problem occurs, examine the EMWS<n>.IGN_OPTPREBIN table. The problem occurs if the WOETREND column contains all 0s.
The node completes successfully. However, the node log contains the following warning:
To work around the problem, turn off the monotonicity constraint for any variable that has all 0s for the WOETREND column. To turn off the monotonicity constraint, select the Advanced Constrained Optimal property. An Advanced Constrained Optimal-WORK.PARAMEDITOR window opens. Change the Apply WOE Monotonicity value to No.
