Bias Of The Cox Model Hazard Ratio, Inger Persson, Harry Khamis

Journal of Modern Applied Statistical Methods

The hazard ratio estimated with the Cox model is investigated under proportional and five forms of nonproportional hazards. Results indicate that the highest bias occurs for diverging hazards with early censoring, and for increasing and crossing hazards under a high censoring rate.

Bias Affiliated With Two Variants Of Cohen’S D When Determining U1 As A Measure Of The Percent Of Non-Overlap, David A. Walker

Journal of Modern Applied Statistical Methods

Variants of Cohen’s d, in this instance dt and d_{adj, has the largest influence on U1 measures used with smaller sample sizes, specifically when n1 and n2 = 10. This study indicated that bias for variants of d, which influence U1 measures, tends to subside and become more manageable, in terms of precision of estimation, around 1% to 2% when n1 and n2 = 20. Thus, depending on the direction of the influence, both dt and dadj are likely to manage bias in the U1 measure quite well for smaller to …}

Some Guidelines For Using Nonparametric Methods For Modeling Data From Response Surface Designs, Christine M. Anderson-Cook, Kathryn Prewitt

Journal of Modern Applied Statistical Methods

Traditional response surface methodology focuses on modeling responses using parametric models with designs chosen to balance cost with adequate estimation of parameters and prediction in the design space. Using nonparametric smoothing to approximate the response surface offers both opportunities as well as problems. This article explores some conditions under which these methods can be appropriately used to increase the flexibility of surfaces modeled. The Box and Draper (1987) printing ink study is considered to illustrate the methods.

Determining The Correct Number Of Components To Extract From A Principal Components Analysis: A Monte Carlo Study Of The Accuracy Of The Scree Plot, Gibbs Y. Kanyongo

Journal of Modern Applied Statistical Methods

This article pertains to the accuracy of the of the scree plot in determining the correct number of components to retain under different conditions of sample size, component loading and variable-tocomponent ratio. The study employs use of Monte Carlo simulations in which the population parameters were manipulated, and data were generated, and then the scree plot applied to the generated scores.

Bayesian Wavelet Estimation Of Long Memory Parameter, Leming Qu

Journal of Modern Applied Statistical Methods

A Bayesian wavelet estimation method for estimating parameters of a stationary I(d) process is represented as an useful alternative to the existing frequentist wavelet estimation methods. The effectiveness of the proposed method is demonstrated through Monte Carlo simulations. The sampling from the posterior distribution is through the Markov Chain Monte Carlo (MCMC) easily implemented in the WinBUGS software package.

The War On Terror: A Utilitarian Analysis, George Nathan Gomme

Undergraduate University Honors Capstones

The intention of this thesis is to explore whether or not the response of the United States of America to terrorist attacks on September 11, 2001 was morally right. It is my contention that the theory best suited to make such a decision is utilitarianism. Specifics as well as flaws of the theory will be explained as a filter through which to better understand and explore the events and the responses of the American government. Application of the theory to the United States government will lead to a determination as to whether or not our actions were morally right. The …

"Offshore” Or “Shorn Off”: The Oecd’S Harmful Tax Competition Initiative And Development In Small Island Economies, Richard Woodward

Books/Book Chapters

The difficulties of developing and executing a sustainable development program in Small Island Economies (SIEs) are well documented. Comparatively small domestic markets, remote export markets, a dearth of natural and human resources, susceptibility to environmental change and natural disasters, plus limitations on the state’s capacity to govern economic activity have narrowed the range of feasible development strategies resulting in a reliance on sectors vulnerable to the vicissitudes of the global economy.

Color And Depression In The Diagnostic Drawing Series, Cara Emily Levitt

EVMS School of Health Professions Theses & Dissertations

One of the most interesting and widely held assumptions by clinicians who used projective drawings was that the absence of color may indicate depression. The research about color’s relationship to depression was ambiguous, limited and dated. In this study it was hypothesized that the absence or presence of color in the Feeling Drawing of the Diagnostic Drawing Series [DDS] will have a positive correlation with a diagnosis of Major Depression. To test this hypothesis the colors both in the DDS archives Major Depression group and comparison group were counted and then statistically analyze to determine if specified colors were present …

It is concluded that data mining is applicable in educational research.

Effect Of Position Of An Outlier On The Influence Curve Of The Measures Of Preferred Direction For Circular Data, B. Sango Otieno, Christine M. Anderson-Cook

Journal of Modern Applied Statistical Methods

Circular or angular data occur in many fields of applied statistics. A common problem of interest in circular data is estimating a preferred direction and its corresponding distribution. It is complicated by the wrap-around effect on the circle, which exists because there is no natural minimum or maximum. The usual statistics employed for linear data are inappropriate for directional data, as they do not account for its circular nature. The robustness of the three common choices for summarizing the preferred direction (the sample circular mean, sample circular median and a circular analog of the Hodges-Lehmann estimator) are evaluated via their …

An Empirical Evaluation Of The Retrospective Pretest: Are There Advantages To Looking Back?, Paul A. Nakonezny, Joseph Lee Rodgers

Journal of Modern Applied Statistical Methods

This article builds on research regarding response shift effects and retrospective self-report ratings. Results suggest moderate evidence of a response shift bias in the conventional pretest-posttest treatment design in the treatment group. The use of explicitly worded anchors on response scales, as well as the measurement of knowledge ratings (a cognitive construct) in an evaluation methodology setting, helped to mitigate the magnitude of a response shift bias. The retrospective pretest-posttest design provides a measure of change that is more in accord with the objective measure of change than is the conventional pretest-posttest treatment design with the objective measure of change, …

Regression By Data Segments Via Discriminant Analysis, Stan Lipovetsky, Michael Conklin

Journal of Modern Applied Statistical Methods

It is known that two-group linear discriminant function can be constructed via binary regression. In this article, it is shown that the opposite relation is also relevant – it is possible to present multiple regression as a linear combination of a main part, based on the pooled variance, and Fisher discriminators by data segments. Presenting regression as an aggregate of the discriminators allows one to decompose coefficients of the model into sum of several vectors related to segments. Using this technique provides an understanding of how the total regression model is composed of the regressions by the segments with possible …

Inferences About Regression Interactions Via A Robust Smoother With An Application To Cannabis Problems, Rand R. Wilcox, Mitchell Earleywine

Journal of Modern Applied Statistical Methods

A flexible approach to testing the hypothesis of no regression interaction is to test the hypothesis that a generalized additive model provides a good fit to the data, where the components are some type of robust smoother. A practical concern, however, is that there are no published results on how well this approach controls the probability of a Type I error. Simulation results, reported here, indicate that an appropriate choice for the span of the smoother is required so that the actual probability of a Type I error is reasonably close to the nominal level. The technique is illustrated with …

Local Power For Combining Independent Tests In The Presence Of Nuisance Parameters For The Logistic Distribution, Walid A. Abu-Dayyeh, Z. R. Al-Rawi, M. M. A. Al-Momani

Journal of Modern Applied Statistical Methods

Four combination methods of independent tests for testing a simple hypothesis versus one-sided alternative are considered viz. Fisher, the logistic, the sum of P-values and the inverse normal method in case of logistic distribution. These methods are compared via local power in the presence of nuisance parameters for some values of α using simple random sample.

The Failure Of Vertical Mergers, Frederick M. Schwarz

Renée Crown University Honors Thesis Projects - All

Creating successful vertical mergers is a challenge for organizations across Corporate America. This honors thesis contains a study of five of those vertical mergers. To complete this study, five mini cases were created that outlined those deals. In addition, statistical analysis of the post merger abnormal returns was completed for each of these deals. Abnormal returns are calculated as the difference between the returns occurring in the post-merger period and the normal returns, i.e., the returns that would have been expected if the merger had not taken place.

This thesis targets the mergers of Viacom Corporation and CBS, Merck Corporation …

Acquisition Of Violations Of English Principle B By Native Speakers Of Japanese Or Chinese, Clarion C. Mendes

Renée Crown University Honors Thesis Projects - All

This work focuses on Principles A and B of Binding Theory as applied to English. While English has a very strict interpretation of Binding Theory, it has a violation of Principle B with sentences with locative prepositional phrases and verb phrases of caused movement or perception.

In contrast, Chinese and Japanese have a very liberal interpretation of Binding Theory. The study is involved with investigating whether or not Japanese or Chinese speakers adapt to the English violation which is typically not taught in a classroom setting, but something acquired through natural exposure.

A custom survey was designed to see if …

The Effects Of The Availability Heuristic On Student's Judgments Of Others Alcohol Consumption, Jennifer Mcenroy

Renée Crown University Honors Thesis Projects - All

The primary purpose of this study was to test the hypothesis that enhancing the availability of images that either portrayed liberal heavy drinking at college or the conservative academic side of college would serve to influence students’ perceptions of peer norms. It was hypothesized that students would rely on the availability heuristic to make judgments of peer norms, so that exposure to a movie clip that emphasized drinking would increase estimates of peer drinking norms when compared with exposure to a movie clip that emphasized academic work. It was further hypothesized that the film clips would assist participants in making …
