Subject: [R] Nonparametric Tukey-type multiple comparisons "Nemenyi" test
Date: Mon, 02 May 2005 16:45:20 -0700
I am trying to do a Nonparametric Tukey-type multiple comparison post-hoc
test to determine which groups are significantly different. I have read
the dialogue on this topic from the R-help, and am still not clear why no
statistical packages include this test as an option? Is it not an
appropriate test to conduct on non-normally distributed data? Is the only
option to calculate it by hand using the (Zar 1996) formula?
Thank you in advance for your help.
