I'm trying to find an example of how to setup a contrast of slopes within JMP. I have found examples which compare multiple categories (http://www.jmp.com/support/help/Regression_Reports.shtml) but not slopes. I tried setting up the SAS example below within JMP but under age*height I don't get an option for LSMeans Contrast (it's grayed out). I have been able to get the LSMeans Contrast option to work for the categorical cross-terms using my data of interest (as opposed to this example) but I don't trust the results. I think I'd be able to figure it out with my data if I understood the example below. Could you point me in the right direction for setting this up in JMP?
