Tusell Additivity Test

Description

Test for an interaction in two-way ANOVA table by the Tusell test.

Usage

tusell.test(Y, alpha = 0.05, critical.value = NA, Nsim = 1000)

Arguments

Y

data matrix

alpha

level of the test

critical.value

result of critical.values function, see Details

Nsim

number of simulations to be used for a critical value estimation

Details

The critical value can be computed in advance and given in the parameter critical value. If not a function critical.values is called to do that.

Value

A list with class "aTest" containing the following components: test statistics stat, critical value critical.value and the result of the test result, i.e. whether the additivity hypothesis has been rejected.
