Applications of analysis of variance in wool marketing
Analysis of variance could be described as a statistical technique for analysing measurements depending on several kinds of effects operating simultaneously so as to decide which kinds of effects are important and to estimate the effects. Although probably not susceptible of a very precise …

Power aspects of analysis of variance in various models.
The object of the present work is to study the robustness of the power in Analysis of Variance in relation to the departures from the in-built assumptions (i) equality of variance of the errors, (ii) statistical independence of the errors, and (iii) normality of the errors in fixed and random …

The use of rank tests in analysis of variance
… based on ranks have been proposed to handle analysis of variance problems. But questions have been raised about the appropriateness of some procedures that are mere rank transformations of normal theory analysis of variance tests.

The development of analysis of variance techniques for angular data.
In many areas of research, such as within medical statistics, biology and geostatistics, problems arise requiring the analysis of angular (or directional) data. Many possess experimental design problems and require analysis of variance techniques for suitable analysis of the angular data. These …

A Radiographic Analysis of Variance in Lower Incisor Enamel Thickness
The purpose of this study was to help predict the enamel thickness of mandibular incisors. At least two direct digital periapical radiographs were made for each of the 80 subjects. Radiographs were scaled to control for magnification errors using dental study models and computer software. …

Analysis of variance of a randomized block design with missing observations
The estimation of several missing values in a randomized block design ls considered. The method used ls that of minimizing the error sum of squares, proposed originally by Yates (1933). Explicit equation for each absent value are derived for all cases in which not more than three values are …

Analysis of variance of a balanced incomplete block design with missing observations
The problem considered in this paper is that of estimating several missing values and analyzing the resulting augmented data in a balanced incomplete block design. The estimates are obtained by Yates' procedure of minimizing the error sum of squares. Explicit formulae are obtained for all cases …

Confidence intervals for the differences between treatment means in an analysis of variance
… the differences between treatment means in an analysis of variance. The intervals have the following properties: (1) The probability that the interval will cover the parameter is greater than or equal to (1 - α), and (2) If the same procedure is applied simultaneously to each of the pO2 …

Analysis of variance of a group divisible singular design with two associate classes with missing observations
… discussed in this paper is the estimation of a single missing observation, two missing observations and several missing observations in a Group Visible (Singular) for Shirley balanced incomplete blocks design with two associate classes. Subsequently the analysis of variance, of the data …

An Analysis of Variance in Teacher Self-Efficacy Levels Dependent on Participation Time in Professional Learning Communities
<p>The purpose of this study was to determine variance in mean levels of teacher self-efficacy (TSE) and its three factors – efficacy in student engagement (EIS), efficacy in instructional strategies (EIS), and efficacy in classroom management (ECM) – based on participation and time spent in …

Fast and stable smoothing spline analysis of variance models for large samples with applications to electroencephalography data analysis
… and algorithm used to fit a smoothing spline analysis of variance (SSANOVA) model are computationally expensive, making a generalized additive model (GAM) the preferred method for multivariate smoothing. In this thesis, I propose various approximations and algorithms to stabilize and speed-up …

Power characteristics of Kramer's method for analysis of variance of a two-way classification with disproportionate subclass numbers
… 321883-887] is extended to give the distribution of Q/X² , where Q is a positive definite quadratic form involving non-central normal variates and X² is an independently distributed chi-square variate. Conditions are given under which the distribution of this ratio reduces to that of non-central …

The interactive effects of data categorization and noncircularity on the sampling distribution of generalizability coefficients in analysis of variance models : an empirical investigation
… Carlo procedures to investigate the effects of data categorization and noncircularity on generalizability (G) coefficients for the one-facet and two-facet fully-crossed balanced designs as well as on the Type I error rates for F tests in repeated measures ANOVA designs. Computer programs were …

Does mentoring cause a person to have learned optimism?
The purpose of the study was to explore "optimism," the characteristics of an optimistic person, and the relationship to the mentoring experience. Are optimistic individuals, likely to engage in helping others through volunteering and mentoring? The study specifically focused on the experiences of …
