Hi everybody,
I'm currently trying to perform Kruskal Wallis test comparing 3 groups with unequal sample size. Does anyone know if it's feasible?
In an attempt to solve the problem I tried to replace the zeros with NaN but it gives me the same results as with zeros.
Function used:
[p,tbl,stats] = kruskalwallis(x);
Best,
Eric

This can be done using the grouping variable option in the kruskalwallis function. See the grouping example in the function's documentation here: Kruskal Wallis - Grouping Example
