Testing for Interaction in Two-Way Random and Mixed Effects Models: The Fully Nonparametric Approach
Testing for Interaction in Two-Way Random and Mixed Effects Models: The Fully Nonparametric Approach
Summary In a recent paper, Gaugler and Akritas (unpublished manuscript) considered testing for no main effect in a two-factor mixed effects design when the traditional assumptions do not hold. Here we extend the nonparametric modeling to the random effects design and consider the problem of testing for no interaction effect. …
