Hi,
i am using adonis on my beta diversity results so that i can find which of my metadata categories contributes the most to the results. Every time i run adonis i get different resuts regarding the significance if i change the order of the metadata categories tested in the commands. The contributions does not really change for each category but their statistical significance does. How can i interpret this?
Thank you very much
Hi @Angeliki,
Could you provide your command and what metadata categories you are comparing?
Thanks!
Hi Angeliki
This is because the ADONIS test partitions the beta diversity distance matrix in the order of your choosing! Changing the formula order changes the test, letting you control for one variable while measuring the variance of another! This is extremely useful.
I love this test. I've written about it before.
If you can share the command like Chloe suggested we can tell you exactly what the test is testing.
