This paper aims at constructing stepwise test procedures based on the Bonferroni Holm principle for a multi way ANOVA Especially for the two way ANOVA it is shown that the procedures keep the multiple level These theoretical results are supplemented by a simulation study to compare the multiple procedures regarding two power concepts and to learn about which of the introduced procedures is the ...

This research is to provide a solution of one-way ANOVA without using transformation when variances are heteroscedastic and group sizes are unequal. Parametric boothstrap test (Krishnamoorthy, Lu, & Mathew, 2007) has been shown to be competitive with many other methods when testing the equality of group means. We extend the parametric bootstrap algorithm to a multiple comparison procedure. Simu...

Abstract– In the present paper, the effect of heat treatment on the surface roughness of AISI 4140 steel has been investigated by use of paired t-test and one way analysis of variance (ANOVA). The paired t-test was performed to determine the differences between the means before and after heat treatment. One way ANOVA was used to further evaluate the effect of heat treatment on the difference in...

Previous research has shown that method two-way with error for multiple imputation in test and questionnaire data produces small bias in statistical analyses. This method is based on a two-way ANOVA model of persons by items but it is improper from a Bayesian point of view. Proper two-way imputations are generated using data augmentation. Simulation results show that the resulting method two-wa...

In this article we consider the Two-Way ANOVA model with unequal cell frequencies without the assumption of equal error variances. By taking the generalized approach to finding p-values, classical F-tests for no interaction effects and equal main effects are extended under heteroscedasticity. The generalized Ftests developed in this article can be utilized in significance testing or in fixed le...

When evaluating the clinical performance of a medical imaging device, multi-reader multi-case (MRMC) analysis is usually applied to account for both case and reader variability. For task that equates quantitative measurement, an agreement such as limits (LOA) method can be used compare different measurement methods. In this work, we introduce four types comparisons; these differ depending on wh...
