Fitting of custom non-linear function

MarkusBJ

I have some data (~100 examples) : 3 attributes (att1, att2, att3) and the label (lab1)

Theory says that
lab1 = p1*att1^2 + p2*(att2^1/2) + p3*exp^(p4*att3) + p5,
where p1..p5 - some parameters

Is it possible to find these parameters by using Rapidminer (non-linear least squares or something)?
Which operators should I use?

Had it not been for p4, I think you could have transform the attributes and run a simple linear regression. I don't know how to do it in RM.

You might want to check R or Formulize (http://www.nutonian.com/eureqa-ii/)
