Creating a basic model to predict likely outcome - Same results?

Nevyn

Hello all,

I wonder if someone can help me, I am a complete noop when it comes to rapidminer so please bare with me! I have created a model which I am trying to use to predict outcomes. Basically my first file contains the ID attribute and the label attribute. The label has 3 outcomes and I want those outcomes overlayed onto a set of other data as a prediction. However when I run this everything comes out exactly the same. i.e confidence for outcome 1 is always 0.621, confidence for outcome 2 is always 0.357 and no 3 is always 0.022. am I using the wrong type of model? Any help would be appreciated.

Thanks

Hello Nevyn

The default model calculates a statistical summary such as the median so it will always give constant values,

Choosing the right model is a very big question but try k-nn to see if you get something different.
