tukeyTest: Tukey test

In scmamp: Statistical Comparison of Multiple Algorithms in Multiple Problems

Description

This function performs the Tukey test

Usage

tukeyTest(data, alpha = 0.05)

Arguments

data	Matrix or data frame where each algorithm is in a column
alpha	Significance level

Details

The test has been implemented according to Test 28 in Kanji (2006).

Value

A list with class "htest" containing the following components: statistic, the value of the statistic used in the test; method, a character string indicating what type of test was performed; data.name, a character string giving the name of the data and diff.matirx, a matrix with all the pairwise absolute difference of average values.
