| dc.description.abstract | AMMI (Additive Main Effect Multiplicative Interaction) model for interactions in two-way table provide the
major mean for studying stability and adaptability through genotype × environment interaction (GEI), which
modeled by full interaction model. Eligibility of AMMI (Additive Main Effect Multiplicative Interaction)
model depends on that assumption of normally independent distributed error with a constant variance. In the
study of genotypes’ resistance, disease and pest (insect) incidence on a plant for example, the appropriateness of
AMMI model is being doubtful. We can handle it by introducing multiplicative terms for interaction in wider
class of modeling, Generalized Linear Models. Its called Generalized AMMI model. An algorithm of iterative
alternating generalized regression of row and column estimates its parameters. GAMMI log-link model will be
applied to the Poisson data distribution. GAMMI log-link models give us good information of the interaction by
its log-odd ratio. | en_US |
