I am a newbie to RapidMiner. I tried converting polynomial to binomial using nominal to binomial operator.

"Award",  "gender",  "smoke" are polynomial attributes. I used nominal to binomial operator but  "award" attribute alone changes to binomial and other two attributes remains the same.

I wonder how this could happen?

Is there any way to convert other attributes too as binomial?

Any help would be very grateful.Please help me in solving this.

Here is the link for the snapshots.


Thanks and regards,

    Hi vishnu,

    the reason for this is that the other two values are already binomial ones. What you are looking for is to force the dichotomization. Please enable "transform binomial" in the parameters tab of the operator.
