Fit polynomial over 8

Mar 19, 2020 1:12 PM
(1258 views)

Hi,

I want to fit polynominal order of 20, but JMP script only allow me to fit polynominal up to 8.

Is there any way that I can do fit polynominal over 9?

Thank you in advance!

Select **Analyze > Fit Model**. Select the predictor column. Change **Degree** to 9. Click **Macros** and select **Polynomial to Degree**.

For example,

Re: Fit polynomial over 8

Hi Mark,

Thank you so much for prompt reply!

I followed your method and it works order of 9 and 10. But, it looks like the maximum order is 10. Is there any way that I can fit over 10, like 11?

Thank you again!

Re: Fit polynomial over 8

You could build your formula in the formula editor and treat it as if it were a nonlinear function.

Re: Fit polynomial over 8

You have answers to your question, but we still do not know the purpose of the plot or the polynomial model. If need a flexible model or interpolator, then you should know that JMP has other options besides a polynomial function for a linear predictor. We have several splines and LOESS, Guassian process models, functional data basis expansion models, and neural networks.
