Value

A list with components `P` (the computed P-value), `stat` (the test statistic, either t or F), `df` (degrees of freedom), `testname` (test name), `statname` (statistic name), `namefun` ("paired_tstat", "rep_aov"), `latexstat` (LaTeX representation of statname), `plotmathstat` (for R - the plotmath representation of `statname`, as a character string), `note` (contains a character string note about the test).

Arguments

tab

a frequency table (an integer `table`, if a `matrix` is provided, it will be coerced to a `table` internally)

Details
