I am performing a three-way ANOVA and I got a significant three-way interaction between the factors. In the process of further analysis, I need to write a contrast statement to compare the differences between levels of a variable (di - 6 levels) at different levels of another variable (dr - 3 levels). But I am not sure how to write the contrast coefficients for this condition. I have attached my data and SAS code. Please give me some input.

Comparing levels to one another is not the place where CONTRAST statements are needed.


Use the LSMEANS statement to compare the levels.

Thank you for your reply. 


If I want to test some customized hypothesis regarding some specific levels of a factor, wouldn't I need to use contrast statement?
