On testing variance components in ANOVA models

Hartung, Joachim; Knapp, Guido - 2000

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...

Inference on the Limiting False Discovery Rate and the P-value Threshold Parameter Assuming Weak Dependence between Gene Expression Levels within Subject

Heller, Glenn; Qin, Jing - In: Statistical Applications in Genetics and Molecular Biology 6 (2007) 1, pp. 14-14

outcome. For each gene, a test statistic is computed to determine if an association exists, and this statistic generates a … normality of the test statistic. The p-values are assumed to be weakly dependent and a quasi-likelihood is used to estimate the …

Order-restricted Dose-related Trend Phi-divergence Tests for Generalized Linear Models

Felipe, A.; Menendez, M. L.; Pardo, L. - In: Journal of Applied Statistics 34 (2007) 5, pp. 611-623

In this paper a new family of test statistics is presented for testing the independence between the binary response Y and an ordered categorical explanatory variable X (doses) against the alternative hypothesis of an increase dose-response relationship between a response variable Y and X...

Multiple Testing. Part I. Single-Step Procedures for Control of General Type I Error Rates

Dudoit, Sandrine; Laan, Mark van der; Pollard, Katherine - In: Statistical Applications in Genetics and Molecular Biology 3 (2007) 1, pp. 13-13

The present article proposes general single-step multiple testing procedures for controlling Type I error rates defined as arbitrary parameters of the distribution of the number of Type I errors, such as the generalized family-wise error rate. A key feature of our approach is the test statistics...
