The Impute node in SAS® Enterprise Miner™ should enable you to specify a Method for each variable that appears in the Impt window. However, if your variable has an Interval measurement level, the Method choices that are presented are incorrect. The problem is that Nominal methods are presented for interval variables. The Interval methods are grayed out.
When a variable is Interval, these interval methods should be available: Andrew's Wave, Huber, Maximum, Mean, Median, Mid-Minimum Spacing, Midrange, Minimum.
To work around the problem, create a separate Impute node for each Interval method that you want. Use the Interval Variable Default Input Method property to specify the method.
EXAMPLE
Suppose that you are using the SAMPSIO.HMEQ data set, and that you want to use the Huber method for CLAGE, CLNO, DEBTINC. You also want to use Mean imputation for the other interval inputs.
Attach an Impute node to the Input Data node. In the Impute node, set Use=No for CLAGE, CLNO, DEBTINC. Run the node. All interval variables except those three use Mean replacement (the Default method).
Attach a second Impute node to the first Impute node. In the second Impute node, set Use=No for all variables except CLAGE, CLNO, DEBTINC. For CLAGE, CLNO, DEBTINC, set Method=Default, Use=Yes. Select OK. Set the Interval Variables Default Input Method to Huber. Run the node.
If you want a third interval variable method, then attach a third Impute node. Use one Impute node per interval input method that you desire.
