Null hypothesis - JMP Custom test

[#1]

Hi All,

I am fitting  a fourth degree polynomial to a dataset.  The equation is.

y = b0 +b1x+ b2x^2 + b3x^ + b4x4 + e

Typically, we null tested is "Ho: b1=b2=b3=b4=0"

However, I want to test if the coefficients are not zero "Ho: b3=b4=0"

How do we do this using JMP 15 custom test?

Thanks

You should do a search on this community discussion board for "custom test". There have been several discussions on how to set up the custom test. Here is one of them: Fit Model - Custom Test and this discussion links to another really good discussion.
