Second Degree Polynomial Parameter Script

Hi All, 

I have a data set (x and y) that I need to approximate to the 2nd degree polynomial (ax2+bx+c) and report "a" value in the "a"-column.

Is there a potential script for this?

Please see JMP table attached.

Thank you All!

Re: Second Degree Polynomial Parameter Script

It is easy to interactively accomplish your task. Select Analyze > Fit Y by X. Cast the x and y columns into their respective analysis roles and click OK. Click the red triangle and select Fit Polynomial , degree 2

Is there a reason that a script is required?

Thank you Mark, I am on this path as well now. It requires some extra work, I thought if someone had the script already - would be more robust.
