For reference, I am using the second method that is described in the technical note that your cited because you do not have JMP Pro. I imported the data from the Excel workbook. The data did not require any further change. I set up the model with plot as a nested random effect. The rest of the model included the variety (nominal modeling type) and harvest data (ordinal modeling type) with a crossed term. The variety does not appear to be significant for either response. Many degrees of freedom go to estimating all the harvest data parameters, though. I tried using the continuous modeling type for harvest data but was not successful.
I saved the script for the Fit Model launch dialog and for the Fit Least Squares platform. I uploaded this data table for you here.
