non-linear multiple regression

Hi... I am trying to fit a non-linear multiple regression. K = A EXP(B X) + C Y + D Z + E. Where K is a response, and X Y Z are variables. A B C D E are the coefficient to determine. I am using JMP pro 8. Please advise which method I can use. Many thanks in advance.

Re: non-linear multiple regression

Hi yp,

You can build your non-linear regression formula in a new column for K.  By creating a new column you preserve the original data in case you lose something along the way to the new formula.

First you need to set up you parameters A through E by opening a the column formula for your new K column.  Right click the column header and select formula.  Once you have that open go to the upper left of the formula dialog box and click the dropdown arrow.  Select Parameters then New Parameter.  Define each with it's corresponding letter and a value.  If you have an idea of what the value is for the parameter plug it in otherwise use 1.

Do this while building your equation.  Based on your input it should look like below:

Use this formula as your X predictor formula in the Nonlinear platform with K as your response.

Say OK and then in the next dialog box Go to converge on a solution with new estimates for A through E.  Make sure to select Save Estimates when you get a solution.  This will save the values of the parameters in the new column.

Best,

Bill
