Hello,

I'd like to know if there are some methods in RM5 to do a scoring analysis (in particular: weighted score tables). I have seen this in SAP BW and I am also looking for it in RM5:

Info about weighted score tables:
English, German


Thank you

    Hi Robert,

    sure, something like this is a piece of cake for RapidMiner. Here is an example process for RapidMiner:

    <?xml version="1.0" encoding="UTF-8" standalone="no"?>
    <process version="5.0">

        <output/>

      </context>

        </process>
      </operator>
    </process>
    The first operator generates data similar to that used in the links you provided. The next operator (Discretize) defines the different age groups. The next three operators map each age group to the value used for scoring. The last operator finally calculates the score and adds it as a new column to your data set.

    I have also uploaded the process to myExperiment and you can easily download and use the process with our new Community Extension. Just search for "Weighted Score Tables" in the myExperiment view of RapidMiner.

    Cheers,
    Ingo
