Bonferroni with unequal sample sizes
Hello-
I have run an ANOVA on 4 treatments with unequal sample sizes (n=9,7,10 and 10). I want to determine where my sig. differences are between treatments using a Bonferroni test, and have run the code:
pairwise.t.test(Wk16, Treatment, p.adf="bonf")
I receive an error message stating that my arguments are of unequal length:
Error in tapply(x, g, mean, na.rm = TRUE) :
arguments must have same length
Is there a way to run this test even with unequal sample sizes?
Thanks.
