Hi, I have a numeric feature - Income with below values. There are 0 values too. I want to perform scaling but cant find an option. I saw this article in the documents section but it doesnt mention the steps in DSS.

Hi,

You can perform scaling on a feature from the Visual Analysis -> Models -> Design Tab -> Feature Handling. Select the feature and in the menu you will have several options to determine rescaling behavior and you can even switch to custom handling. Once you've confirmed the feature handling you can retrain your model.

Hope this helps.
