Alternative estimation methods in structural equation modeling with LISREL-7: Effects of noncontinuity and nonnormality of variables with varying sample sizes
The accuracy of alternative estimation methods (i.e., ML, GLS, and WLS) in structural equation modeling was investigated under two kinds of sample sizes--150 and 500--with advantage of Monte Carlo study. Four types of variables--continuous-normal, continuous-nonnormal, discrete-normal, and …

On Approximation and Optimal Control of Nonnormal Distributed Parameter Systems
… attention has been directed toward studying the nonnormality of linearized problems and developing convergent numerical schemes for simulation of these sytems. Numerical schemes for optimal control problems often require additional properties that may not be necessary for simulation; these …

The effect of non-normality on the power of the test of a two-way classification, fixed effects model--no interaction
This thesis considers the effect of nonnormality, in terms of skewness and kurtosis, on the power of the analysis of variance test for a two-way classification, fixed effects model (with two replicates and no interaction). Most of the populations considered were only moderately non-normal, that is, …

Stochastic dynamics in spatially extended physical and biological systems
… (2) the amplification effect of nonnormality on stochastic Turing patterns in reaction diffusion systems, and (3) the velocity statistics of edge dislocations in plastic deformation of crystalline material. In Part I, I present a new model for the origin of homochirality, the …

Becoming and Thriving as an EFL Instructor: Exploring Key Factors Contributing to Positive Identity Construction
… to correlation analysis using SPSS. Due to nonnormality in the data, Kruskal-Wallis and Spearman’s rho tests were employed to derive referential outcomes. Data analysis revealed teaching experience and overseas experience were not influencing factors, whereas professional title was important …

Fault detection in multivariate processes : handling autocorrelation, contamination, and small sample sizes in engineered systems.
… from out-of-control behavior that account for nonnormality and dependence. An extensive literature review covering approaches for handling small sample sizes and contamination is presented, including examples illustrating the shortcomings and trade-offs of existing methods, and finally, a novel …

Fatigue analysis for non-normal stochastic stress
… It is also noted that the influence of nonnormality is affected not only by the kurtosis of the stress process, but also by the slope of the S-N curve (which is a material property).

Toward A More Comprehensive Model of Economic Vulnerability, Family Stress, and Children’s Social-Emotional Competence
… samples in which missing data and data nonnormality is treated in different ways, using sensitivity analyses to assess the robustness of the findings across the samples. Interestingly, the comprehensive model did not hold. In testing this model with the TCS data, there were a number of …

New control charts for monitoring univariate autocorrelated processes and high-dimensional profiles
… profile with noisy components that may exhibit nonnormality, variance heterogeneity, or correlation between profile components. A profile describes the relationship between a selected quality characteristic and an input (design) variable over the experimental region. Exploiting a discrete …
