Comparative Power Of The Anova, Randomization Anova, And Kruskal-Wallis Test
… in computing capabilities, the permutation ANOVA has been explored as an alternative to the ANOVA under non-normal conditions to rehabilitate the loss of statistical power. Since the permutation ANOVA does not operate under the assumption of normality and uses actual scores, many researchers …

Functional Anova Models With Application to Corporate Bonds
… approaches for testing hypotheses in functional ANOVA models. While testing different hypotheses, we proposed four different approaches for resampling data under the null hypothesis of no effect of the factors. They include bootstrapping method with two separate resampling approaches: resampling …

An Empirical Comparison of Four Data Generating Procedures in Parametric and Nonparametric ANOVA
… and within-subjects analysis of variance (ANOVA). The traditional parametric F tests and their nonparametric counterparts, the Kruskal-Wallis (KW) and Friedman (FR) tests, were selected to be used in this investigation. The four data transformations produce non-normal distributions that …

Repeated Measures ANOVA with Latent Variables: A New Approach Based on Structural Equation Modeling
… repeated measures analysis of variance (L-RM-ANOVA) as an alternative approach to traditional repeated measures ANOVA (RM-ANOVA). Traditional RM-ANOVA are commonplace for investigating phenomena in the social and behavioral sciences, and researchers often use RM-ANOVA as a statistical method …

Use of the Unbalanced Nested ANOVA to Examine the Factors Influencing Student Ratings of Instructional Quality
This study utilized a 5-way unbalanced nested ANOVA model to evaluate student ratings of teaching. An effective sample included three types of course motivation, four course levels, seven levels of class size, 9 types of academic discipline, and about 3,754 classes with a total of 106,303 students. …

A type I error investigation of modified Scheffe-based multiple-comparison procedures in factorial ANOVA, MANOVA, and multiple-regression situations
The present study extends the previous one-way ANOVA multiple-comparison findings of Meyers and Beretvas (2003) to interaction comparisons in factorial ANOVA designs, one-factor MANOVA comparisons, and tests of partial regression coefficients in multiple regression, in specific regard to the …

An analysis of the periodicity of the cell cycle and apoptotic regulatory proteins in prostate xenografts using anova and cosinor methods
… Statistical analysis of the mice with the ANOVA and the COSiNOR methods showed that selenium treatment was most effective at HALO 13 at decreasing cell cycle and apoptosis-related proteins for ALVA-3 1. For PC-3 tumor lines, HALO 7 proved to be of highest expression while HALO 13 showed the …

Application of ANOVA for the analysis of temporal and spatial differences in the length of pelagic goby preyed on by Cape fur seals in the coasts of Namibia
… more components (Wayne, 1999). In this thesis, ANOVA was used to uncover the differences in goby length preyed on by three different colonies of fur seals at the Namibian coast. Moreover, ANOVA was used to investigate temporal differences in lengths of goby preyed on by fur seals in each …

METHODOLOGIES FOR ESTIMATING REPEATABILITY AND REPRODUCIBILITY VARIANCES IN MULTIVARIATE DATABASES
… to analyze such data analysis of variance (ANOVA) or multivariate ANOVA (MANOVA) is used. However direct application of these methodologies to spectrum obtained from structured experimental studies is inappropriate or impossible. More complex data analyses methodologies are required to …

The Applications of Raman Spectroscopy Assisted Urinalysis: Hematuria and Bladder Cancer Detection
… components (DAPC), analysis of variance (ANOVA), pairwise ANOVA, leave-one-out cross-validation (LOOCV), and partial least squares regression (PLSR). These components of the data pipeline serve to output qualitative or quantitative data, depending on the application. The Rametrix toolbox …

The Ontogeny of Thermoregulatory Abilities in Neonatal Cotton Rats and Montane Voles
… for both species (repeated measured two-way ANOVA: P<0.001). The response to NE increased with age for both cotton rats and montane voles (repeated measures two-way ANOVA: P<0.001). The number of NE treatments that an animal received did not effect its NE-induced metabolism at day 12 for …

The Involvement of Progesterone in Glial Cell Viability
… peroxide. Data were analyzed using a 2-way ANOVA and a Tukey’s post hoc test with a p-value of less than 0.05 being significant. Viability did not differ significantly between stressed and unstressed cells (2-way ANOVA, F9,30=1.673, P=0.211) or between cells receiving varying concentrations …

Eye Movements of Highly Identified Sport Fans
… logo appears without the other. A mixed-model ANOVA was conducted to examine the impact of set type on total time to identify the target. The ANOVA yielded no main effects or interactions. The second hypothesis under study states that highly identified UK fans detect the UT logo more slowly …

Acculturation Level, Generational Status and Gender: Their Role in Acculturative Stress in Young Adolescent Mexican Americans
… product moment correlation (r=.44) and the ANOVA between the mean acculturation score and generational status were significant. However, the mean acculturation score from this study was considerably lower than the ARSMA-II score; therefore, new acculturation levels were developed to …

Attitudes and Behaviors Toward Weight, Body Shape and Eating in Male and Female College Students
… and perceived body weight was also assessed. ANOVA suggested that as actual body mass index increased, in general, attitudes and behavior toward weight, body shape and eating increased. A two-tailed t-test suggested that males and females differed significantly with regards to attitudes and …

Examining Beginning year Writing Production of First Graders: Lined Versus Unlined Paper
… this study was analyzed using a three-factor ANOVA model. The results of the ANOVA model indicate beginning emergent writers produce more letters and words on unlined paper than on lined paper. This evidence supports observations by Clay (1993) and Avery (1993) that early emergent writers are …

Attitude Formation & Persuasion Via Reactance: No, You Can't – Yes, I Can!
… collected from MTurk. Both repeated measures ANOVA and double sequential mediation analyses were employed to investigate hypotheses; the results suggested that the attempt to induce reactance was unsuccessful. Both repeated measures ANOVA and double sequential mediation analyses were employed …
