In this paper, we seek to derive the statistical methods which enable one to perform pairwise comparisons in a two-way analysis of covariance model. The overall family-wise type I error rate is controlled at a designated level. The procedures are outlined for simultaneous inferences among ...
Two-way ANOVA and ANCOVA In this tutorial we discuss fitting two-way analysis of variance (ANOVA), as well as, analysis of covariance (ANCOVA) models in R. As we fit these models using regression methods much of the syntax from the multiple regression tutorial will still be valid. However...
uniform covariance structureWe consider some estimation and distribution problems encountered in a two way analysis of variance model with only one observation per cell, errors correlated in one level, and the variances are not necessarily equal. The independence criteria for the row and interaction ...
Statistical analysis of the interaction effect in a two-way analysis of a vari-ance/covariance model (typically unbalanced) is often performed to provide some additional support for the assessment of the main effect of interest. For exam-ple, an analysis of treatment-by-center interaction, in ad...
A functional two-way analysis of variance is proposed. Functional data analysis tools, based on Cuesta-Albertos and Febrero-Bande [20], are used. The method is adapted to consider the dependence that exists among the data because of the experimental setting. A parametric bootstrap is proposed ...
