Abstract:In analysis of variance the assumption of non-additivity has more serious consequences on the interpretation of results than the assumptions of non-normality or non-homogeneity of variances.TUKEY (1949, 1955) suggested a procedure for separating out a single degree of freedom for non-additivity ror two factor and multi-factor experiments, respectively. In multifactor experiments Tukey's procedure does not indicate which combinations of the factors contribute to non-additivity. In this paper a procedure is pro… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
