Fit polynomial over 8

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!

Re: Fit polynomial over 8

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!

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.
