Hypothesis Testing and Multiplicative Interaction Terms

HYPOTHESIS TESTING FOR AN EXCHANGEABLE NORMAL DISTRIBUTION

Consider an exchangeable normal vector with parameters ????2, and ?. On the basis of a vector observation some tests about these parameters are found and their properties are discussed. A simulation study for these tests and a few nonparametric tests are presented. Some advantages and disadvantages of these tests are discussed and a few applications are given.

LINEAR HYPOTHESIS TESTING USING DLR METRIC

Several practical problems of hypotheses testing can be under a general linear model analysis of variance which would be examined. In analysis of variance, when the response random variable Y , has linear relationship with several random variables X, another important model as analysis of covariance can be used. In this paper, assuming that Y is fuzzy and using DLR metric, a method for testing ...

Hypothesis-Testing Processes in Social Interaction

This research is concerned with the processes by which individuals use social interaction to actively test hypotheses about other people. In four separate empirical investigations, female participants were provided with hypotheses about the personal attributes of other individuals ("targets"). Participants then prepared to test these hypotheses (i.e., that their targets were extraverts or that ...

Parametric bootstrap methods for testing multiplicative terms in GGE and AMMI models.

The genotype main effects and genotype-by-environment interaction effects (GGE) model and the additive main effects and multiplicative interaction (AMMI) model are two common models for analysis of genotype-by-environment data. These models are frequently used by agronomists, plant breeders, geneticists and statisticians for analysis of multi-environment trials. In such trials, a set of genotyp...
