Multivariate Kruskal-Wallis test

[mgb38]

Hello!

I have several count values for two groups in several variables, as seen on the plot.
I have seven observations in the purple group and 74 in the grey group.
I have 10 variables (x axis).

I want to compare the distributions of the purple and grey groups in each of the 10 variables.

I thought I could make a Kruskal-Wallis test, but multivariate.
What do you think? How to implement it in R?

Thanks!!

LC

If you have counts you should look into count regression models such as Poisson of negative binomial regression.
