midrangeMCP: The R Package for multiple comparisons based on the Range and Midrange distributions
Conteúdo do artigo principal
Resumo
This paper introduces four new types of multiple comparison procedures. Their performance was evaluated in large experimental scenarios using Monte Carlo simulations, with a focus on comparing experimentwise error rates and statistical power against those of the traditional Tukey, Student-Newman-Keuls (SNK), and Scott-Knott tests. To facilitate the practical application of these methods, we developed the R package midrangeMCP. The proposed procedures are: the Midrange Tukey test (TM), the Midrange Student-Newman-Keuls test (SNKM), the Mean Grouping based on the Midrange (MGM), and the Mean Grouping based on the Range (MGR). The TM, MGM, and MGR tests outperformed their classical counterparts (Tukey and Scott-Knott), except under scenarios with partially true null hypotheses. The SNKM test was the only one that consistently underperformed compared to its original version (the SNK test) across all evaluated scenarios. Among the proposed methods, the MGM test stood out for its superior performance and its additional advantage of avoiding ambiguity in group assignments.
