twlStat {peramo}

Test Statistics for Two-Way Layout Permutation Test

Description

twlStat computes statistics for twl. This is not meant to be called directly.

Usage

twlStat(df, env = parent.frame())

Arguments

df

a data frame with the levels of the two main factors as the first and second columns and the measurement of responses as the third column.

env

an environment, to access outer scope variables.

Value

twlStat returns a list with at least 4 components:

Fs

the F statistics for global test.

F.main1 and F.main2

the F statistics for the first main factor and the second main factor.

F.int

the F statistic for the interaction.

In case of multiple comparisons, additional components are:

avg or avg.main1 and avg.main2

the mean responses for multiple comparisons.

d.main1sub and d.main2sub or d.main1 and d.main2

the differences in means.

mad.main1sub and mad.main2sub or mad.main1 and mad.main2

the maximum absolute differences in means.
