OIKAWA, Sérgio Minoru and IEMMA, Antonio Francisco. Statistical hypotheses with unbalanced data in models with three factors of fixed nested effects. Sci. agric. [online]. 1999, vol.56, n.4, suppl., pp. 1123-1134. ISSN 1678-992X. http://dx.doi.org/10.1590/S0103-90161999000500014.
The aim of this work is to formalize the terms of the respective sums of squares and more usual hypotheses tested in the models with three factors of fixed nested effects, for unbalanced data. It also discusses the problem of the interpretation of the hypotheses associated to the sums of squares, and comparisons are made for the results provided by some statistical softwares.
Keywords : unbalanced data; sums of squares; testable hypotheses; statistical softwares.
