In this paper we derive asymptotic x 2 - tests for general linear hypotheses on variance components using repeated variance components models. In two examples, the two-way nested classification model and the two-way crossed classification model with interaction, we explicitly investigate the...

A confidence interval for the between group variance is proposed which is deduced from Wald’s exact confidence interval for the ratio of the two variance components in the one-way random effects model and the exact confidence interval for the error variance resp. an unbiased estimator of the...

Positive estimators of the between-group (between-study) variance are proposed. Explicit variance formulae for the estimators are given and approximate confidence intervals for the between-group variance are constructed, as our proposal to a long outstanding problem. By Monte Carlo simulation,...

Die Varianzanalyse ist als methodisches Instrumentarium an allen empirisch und experimentell arbeitenden Wissenschaften bzw. Wissenschaftsbereichen orientiert. Sie stellt einen umfangreichen Kanon von einfachen, intuitiv sofort einsichtigen, bis hin zu komplizierten, tieferliegend zu...
