Hi Markus,

I'm curious: How do you want to calculate the deviation for one single attribute?

Anyway I think you will have to incorporate the script operator to get access to the single components of the formular. The linear regression model is a FormularProvider class, this should give you a good interface to retrieve the coefficients.

If you convert them to a AttributeWeight object, you can apply this to do the multiplication for the whole example set. Might be this is of help depending on how you will answer my question above

Greetings,

Sebastian
