How to analyze a 4x4 Latin square design?

Hello. I am new to JMP. I am still figuring out how to do Latin square designs here. I cannot find any intuitive tutorials here or even in youtube. Here is my sample data ( I got this from Latin square design in R tutorial in Google): 

My treatment of interest is the varieties and row and column are your blocking variables.

First, make sure that the Row and Columns use the Nominal modeling type. Second, follow these steps:

 

  1. Select Analyze > Fit Model
  2. Select Yield and click Y.
  3. Select Row, Column, and Varieties, and click Add.
  4. Click Run.

The Latin square design that you used is simply a one-factor design for four levels, with two blocking variables, each at four levels. This analysis should be correct.

Small, optional but recommended addendum to the above instructions:

3.5 Change the Attribute of Row and Column to Random, as blocking factors should typically be treated as random effects, not fixed, for improved inferential properties.

Basically just like factorial design but no interaction terms?

There is only one factor, so there are no interaction effects.
