For Deming regression, perhaps Fit Orthogonal would be useful for you? It's available under the Red Triangle in Fit Y by X. There are different options depending on how you want to account for differences in the variances of X and Y.
Thanks a lot for towards the menu.The graph axis options mentioned would be helpful for fast judgement and as guide to easily see offset and/or change in gradient. As demonstrated in folllowing blog:
The Method Comparison Add-In by Russ Wolfinger does include a Passing-Bablok and Deming regression. You can download it from here:https://community.jmp.com/t5/JMP-Add-Ins/Method-Comparison/ta-p/21520
It is quite "old", so I am not sure if there are any updates and if it still is working. But maybe worth a look.
The author (Russ Wolfinger) just commented in that thread that it could be time for JMP to add the functionality as a specific platform, not as an Add-In, so it is justifiable.
I would not only go for Deming regression but a Method comparison platform including Passing-Bablok, so that it can be used under regulatory guidelines.
