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.
Design of ExperimentsRe: How to analyze a 4x4 Latin square design?There is only one factor, so there are no interaction effects.
Re: How to analyze a 4x4 Latin square design?Basically just like factorial design but no interaction terms?
Re: How to analyze a 4x4 Latin square design?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.
Re: How to analyze a 4x4 Latin square design?First, make sure that the Row and Columns use the Nominal modeling type. Second, follow these steps:
- Select Analyze > Fit Model
- Select Yield and click Y.
- Select Row, Column, and Varieties, and click Add.
- 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.
