Multiple comparison tests are usually used to compare groups based on the
confidence region about the mean. Some great packages, like agricolae,
proposes grouping information based on statistical tests. I am looking for
a way to perform such a test, but based on the confidence region about the
whole population. I tried to hack LSD.test and HSD.test functions
(agricolae), without much success.
(1) Is this valid to use multiple comparisons across population?
(2) If it is, anyone knows how I could do that?
Kind Regards,
