How to calculate 'slope' or gradient

[#1]

I am looking for a way to calculate the slope or gradient of data. I need to do the same function as slope (X1:X4, Y1:Y4) in excel but to be able to program it into a jmp script.

Regards

Steve

Fit Y by X will give you a slope when both X and Y are continuous. I can't help you with scripting.
