Hi,
I'm trying to make a simple crosstable in a classification problem and since I'm quite new to rapidminer I have no idea how to.
I have a table consisting of two columns and many rows. First column is the ID-label: 1 for "good" customers and 0 for "bad" customers. The second column is consisting of different categories.

I want to count how many "good" customers I have in each category using rapidminer. How do I set up the operators?

    Hi,

    if I understand you correctly, the name of the operation you want perform is "aggregation". To do this in RapidMiner, you can use the Aggregate operator. Select your ID attribute and the category attribute as group attributes, and define the "count" aggregation in the aggregation attributes parameter.

    For a general introduction to RapidMiner and its concepts, I'd like to direct you to the video tutorials on our website.

    Best regards,
    Marius
