How to use Polynomial Regression in rapidminer correctly

rookie

          Hello, everyone. This is my first forum post asking questions about polynomial regression in rapidminer.

The original data is：x:4194.06 3466.45  2070.08   874.98  corresponding to   y：91540.07  109460.36  120338.64  102182.19

As shown in the first flow, the first result expression is obtained by using the polynomial regression operator.

     I want to ask why the results of the two processes are not the same, the original data presents a quadratic nonlinear relationship, and why the quadratic expression cannot be made by polynomial regression. 

Thanks you very much!

Hi @rookie,

Thanks for sharing the data and process.

If we have got four (4) example and train a polynomial regression, we may fail for the model. So I filled up the gap with interpolation to add more data here. Also this Polynomial regression will not perform well without the normalization...

Process attached here for your reference.
