mw.test performs Mann-Whitney U test for two samples.
mw.test(formula, data, alpha = 0.05, na.rm = TRUE, verbose = TRUE)A list with class "owt" containing the following components:
the Z statistic.
the p-value of the test.
the level of significance to assess the statistical difference.
a data frame containing the variables in which NA values (if exist) are removed.
a formula of the form lhs ~ rhs where lhs gives the sample values and rhs the corresponding groups.
a formula of the form lhs ~ rhs where lhs gives the sample values and rhs the corresponding groups.
a tibble or data frame containing the variables in the formula formula
the level of significance to assess the statistical difference. Default is set to alpha = 0.05.
a logical value indicating whether NA values should be stripped before the computation proceeds.
a logical for printing output to R console.
