Hi, I am new to RapidMiner.
I would like to predict Credit Payment 'yes or no' outcome with at least 2 method (e.g Naive Bayes/Decision Tree/k-mean etc.), however all of the prediction returns a no.
Unlike a usual yes/no this attribute has 3 values in the excel data: yes, no and unknown.
I am using Naive Bayes, decision tree and have set the attribute to label, polynominal for prediction.
Appreciate any help in advance.
