The goodness-of-fit tests for geometric models
We propose two types of goodness-of-fit tests for geometric distribution and for a bivariate geometric distribution called BGD(B&D), based on their probability generating function (PGF). The first type is a special-case application of the general testing procedure for discrete distributions …

GOODNESS OF FIT TESTS FOR GENERALIZED LINEAR MIXED MODELS
… (GLMMs) are widely used for regression analysis of data, continuous or discrete, that are assumed to be clustered or correlated. Assessing model fit is important for valid inference. We therefore propose a class of chi-squared goodness-of-fit tests for GLMMs. Our test statistic is a quadratic …

A Jackknife Empirical Likelihood Approach To Goodness Of Fit U-Statistic Testing With Side Information
<p>Motivated by applications to goodness of fit U-statistics testing, the jackknife empirical likelihood of Jing, <em>et al.</em> (2009) is justified with an alternative approach, and the Wilks theorem for vector U-statistics is proved. This generalizes Owen's empirical likelihood theorem for a …

Reflections on diversity: Graduate perceptions of campus climate at Dallas Theological Seminary, 1996-2005.
The purpose of this study was to determine how graduates of master's degree programs perceived the ethnic and cultural climate at Dallas Theological Seminary (DTS) during their enrollment there. The population (N=2,223) consisted of graduates of master's degree programs who attended Dallas Seminary …

Graduate Professional Training in Christian Education at Dallas Theological Seminary and Alumni Perceptions of Program Quality
This study assessed the quality of graduate professional training in Christian education at Dallas Theological Seminary (DTS) in terms of the perceptions of program alumni. The subjects of the investigation were 780 alumni who graduated from DTS between 1984 and 2000. The Christian Education …

On estimation and goodness-of-fit testing for the Pareto distribution
The Pareto distributions are a class of distributions containing several members with varying levels of flexibility. Two of these members, the Pareto Type I and the Lomax distributions, are of particular interest in this thesis. The Pareto Type I distribution is a popular choice of model in many …

Kolmogorov-Smirnov test for grouped data
… grouped samples. It constitutes an application of W. J. Conover's procedure, which was originally designed for calculating exact critical levels for test with discrete distributions. This test extends the goodness-of-fit test to samples which are grouped into intervals. Critical levels in the …

Approximating the distributions of x2-type mixtures via matching four cumulants
Nonparametric goodness-of-fit tests often result in test statistic which can be written as a random variable of chi-square-type mixtures. Zhang (2003) proposed to approximate its distribution using a random variable of form chi-square-type mixtures via matching the first three cumulants. In this …

John Nelson Darby: His Contributions to Contemporary Theological Higher Education
This study investigated the contributions of John Nelson Darby to selected institutions of contemporary theological higher education. A qualitative approach to the investigation was employed. Archival foraging occupied a greater part of the research data and yielded rich returns as evidenced in the …

Rationality or irrationality of preferences? A quantitative test of intransitive decision heuristics
In this paper, I present a comprehensive analysis of two decision heuristics that permit intransitive preferences: the lexicographic semiorder model and the similarity model. I also compare these two intransitive decision heuristics with transitive linear order models and two simple transitive …

A study of probability distributions of DCT coefficients in JPEG compression
… energy compaction properties that rival that of the ideal Karhunen-Loeve Transform. Lossy compression in JPEG is achieved by distorting 8x8 block DCT coefficients through quantization. It has been shown in literature that DC block DCT coefficients are Gaussian probability distributed and AC …

Modeling with bivariate geometric distributions
… components which were subject to different types of failures. Systems with two components having frequency counts in the domain of positive integers, and the survival time of each component following geometric or mixture geometric distribution can be classified into this category. Examples of such …

Sequential analysis of categorical data
Using a variance-stabilizing transformation of the non-centralχ² distribution and Wald's sequential probability ratio test, procedures have been developed for sequential analysis of categorical data group-wise. These procedures' enables (i) a simple hypothesis to be used for the alternative …

A Replication Study of Personality Types of Students in a Professional Pilot Baccalaureate Degree Program
<p>The personality types and learning styles of students have been studied in several populations, yet the research analyzing aviation students is lacking. A replication study assessed the distribution of personality types of students enrolled in the aeronautical science baccalaureate degree …

The impact of spirituality on the self-reported recovery of adults who experienced childhood trauma
… childhood trauma, and who had a higher sense of personal meaning or spirituality, would have improved mental health and lower trauma symptoms such as depression, lower self-esteem, anxiety, dissociative disabilities, PTSD, and the like.</p> <p>Method: 115 participants were randomly selected …

Maximum empirical likelihood estimation in U-statistics based general estimating equations
<p>In the first part of this thesis, we study maximum empirical likelihood estimates (MELE's) in U-statistics based general estimating equations (UGEE's). Our technical maneuver is the jackknife empirical likelihood (JEL) approach. We give the local uniform asymptotic normality condition for the …

High School Hazing: A Study of the Autobiographical Memories of Entering First Year College Students
The problem: The purpose of the study is to determine if relationships exist between autobiographical memories of entering first year college students of their high school hazing experiences and demographic variables. Hazing is defined as any humiliating or dangerous activity expected of students …
