basis function details from the prediction ?

[adumudaliar]

Hello, Since MARs build a model which is weighted sum of basis functions..of the form f(x) = c1B1 + c2B2 + c3B3 + ...+ ciBi

where Bi is a Basis function and ci is a constant coefficient.

is it possible to get the individual value of ciBi for each prediction from the PyEarth implementation ?

Hello,

yes it is possible through the transform method. You can look here : http://contrib.scikit-learn.org/py-earth/content.html#pyearth.Earth.transform

@adumudaliar Yes. Adding to what @mehdidc wrote, the transform method gives your Bi's and your ci's are in the coef_ attribute. Closing, but please post if you find this doesn't work for you.
