I can run a simple ANOVA test in JMP, but I've been trying for a little while now to find out how to run a Multifactor ANOVA test. Any suggestions for how to do this?

Thank you!

Hi sblacklow,

Using **Analyze > Fit Model** you can specify your multi factor ANOVA manually or using the Macro > Full Factorial after selecting your factors in the column list. Here is a PDF showing the steps for fitting a 2-way factorial ANOVA (which generalizes to the higher-way designs):

http://www.jmp.com/academic/pdf/learning/04_two_way_factorial_anova.pdf

The steps for a 3 or higher-way ANOVA are identical -- when you use the "Macro" for "Full Factorial" JMP will populate the *Model Effects* section with the main effects, 2-way interactions, the 3-way interactions, etc. Be sure that your predictor variables are all marked as Nominal.

I hope this helps!

Julian

Hi again,

I just saw how long ago you posted this so you may no longer be using the community board, but hopefully you found your answer!

Multifactorial ANOVA can be run using Fit Model under Analyze. In the Fit Model, add your dependent variable in Y and add all independent variables in Construct Model Effects and select "Factorial Sorted" under "Macros." This will enable you to analyze both main effects and interaction between factors.
