Hi, I need to compare the slopes and intercepts of 4 lines (linear regression y=ax+b) using jmp to see if any of them are similar or if they are significantly different from each other. Can anyone direct me towards a tutorial or a help document indicating the steps of how to do this. I am assuming I need to do an ancova test but have no clue how to setup the problem in jmp or if this is even the right test to do. Any help will be highly appreciated. Thanks!
