Analysis of variance (ANOVA), the workhorse analysis of experimental designs, consists of F-tests of main effects and interactions. Yet, testing, including traditional ANOVA, has been recently critiqued on a number of theoretical and practical grounds. In light of these critiques, model comparison and model selection serve as an attractive alternative. Model comparison differs from testing in t...

there are many parameters that affect the sheet hydroforming process such as fluid pressure, material properties, interfacial friction between blank and tool surfaces, etc. in this paper, a fem-based taguchi method is used to determine the effects of forming parameters on the quality of part formability in the process of hydrodynamic deep drawing assisted by radial pressure. four important form...

This paper aims to improve a fine lapping process of hard disk drive (HDD) lapping machines by removing materials from each slider together with controlling the strip height (SH) variation to minimum value. The standard deviation is the key parameter to evaluate the strip height variation, hence it is minimized. In this paper, a design of experiment (DOE) with factorial analysis by twoway analy...

This paper considers a nested error component model with unbalanced data and proposes simple analysis of variance (ANOVA), maximum likelihood (MLE) and minimum norm quadratic unbiased estimators (MINQUE)-type estimators of the variance components. These are natural extensions from the biometrics, statistics and econometrics literature. The performance of these estimators is investigated by mean...

ard analysis of variance (ANOVA) of the database. This method is fast, accurate, and it provides suitable confidence limits for the ICC estimate. The other method is of Monte Carlo type. It is based on a permutation resampling procedure, which is computationally more demanding and more sensitive to missing data than the ANOVA method. However, this approach is distribution free and much more fle...

in this paper the main objective is to quantify and compare the instantaneous value of heart rate for normal breathing patterns during meditation and non meditation conditions. this paper involves analysis of variance (anova) technique for the analysis of the heart rate variability patterns during the meditative and non meditative states. the analysis is divided into three stages i.e. data acqu...
