A place to ask questions about methods in Orange and how they are used and other general support.
is there any ready tool for polynomial regression in Orange?
Clarification: What I mean is **multivariate ** polynomial regression of the type
Y = c + a1*x1 + a2*x1^2 + a3^x1^3 + b1*x2 + b2*x2^2 + b3*x2^3
Unfortunately no. You could try SVM with a polynomial kernel, although this also includes mixed terms.
