Assessing Trends: Monte Carlo Trials With Four Different Regression Methods, Daniel R. Thompson

Journal of Modern Applied Statistical Methods

Ordinary Least Squares (OLS), Poisson, Negative Binomial, and Quasi-Poisson Regression methods were assessed for testing the statistical significance of a trend by performing 10,000 simulations. The Poisson method should be used when data follow a Poisson distribution. The other methods should be used when data follow a normal distribution.

Approximate Bayesian Confidence Intervals For The Mean Of A Gaussian Distribution Versus Bayesian Models, Vincent A. R. Camara

Journal of Modern Applied Statistical Methods

This study obtained and compared confidence intervals for the mean of a Gaussian distribution. Considering the square error and the Higgins-Tsokos loss functions, approximate Bayesian confidence intervals for the mean of a normal population are derived. Using normal data and SAS software, the obtained approximate Bayesian confidence intervals were compared to a published Bayesian model. Whereas the published Bayesian method is sensitive to the choice of the hyper-parameters and does not always yield the best confidence intervals, it is shown that the proposed approximate Bayesian approach relies only on the observations and often performs better.

Semi-Parametric Of Sample Selection Model Using Fuzzy Concepts, L. Muhamad Safiih, A. A. Kamil, M. T. Abu Osman

Journal of Modern Applied Statistical Methods

The sample selection model has been studied in the context of semi-parametric methods. With the deficiencies of the parametric model, such as inconsistent estimators, semi-parametric estimation methods provide better alternatives. This article focuses on the context of fuzzy concepts as a hybrid to the semiparametric sample selection model. The better approach when confronted with uncertainty and ambiguity is to use the tools provided by the theory of fuzzy sets, which are appropriate for modeling vague concepts. A fuzzy membership function for solving uncertainty data of a semi-parametric sample selection model is introduced as a solution to the problem.

Performance Ratings Of An Autocovariance Base Estimator (Abe) In The Estimation Of Garch Model Parameters When The Normality Assumption Is Invalid, Daniel Eni

Journal of Modern Applied Statistical Methods

The performance of an autocovariance base estimator (ABE) for GARCH models against that of the maximum likelihood estimator (MLE) if a distribution assumption is wrongly specified as normal was studied. This was accomplished by simulating time series data that fits a GARCH model using the Log normal and t-distributions with degrees of freedom of 5, 10 and 15. The simulated time series was considered as the true probability distribution, but normality was assumed in the process of parameter estimations. To track consistency, sample sizes of 200, 500, 1,000 and 1,200 were employed. The two methods were then used to analyze …

A Linear B-Spline Threshold Dose-Response Model With Dose-Specific Response Variation Applied To Developmental Toxicity Studies, Chin-Shang Li, Daniel L. Hunt

Journal of Modern Applied Statistical Methods

A linear B-spline function was modified to model dose-specific response variation in developmental toxicity studies. In this new model, response variation is assumed to differ across dose groups. The model was applied to a developmental toxicity study and proved to be significant over the previous model of singular response variation.

Jmasm28: Gibbs Sampling For 2pno Multi-Unidimensional Item Response Theory Models (Fortran), Yanyan Sheng, Todd C. Headrick

Journal of Modern Applied Statistical Methods

A Fortran 77 subroutine is provided for implementing the Gibbs sampling procedure to a multiunidimensional IRT model for binary item response data with the choice of uniform and normal prior distributions for item parameters. In addition to posterior estimates of the model parameters and their Monte Carlo standard errors, the algorithm also estimates the correlations between distinct latent traits. The subroutine requires the user to have access to the IMSL library. The source code is available at http://www.siuc.edu/~epse1/sheng/Fortran/MUIRT/GSMU2.FOR. An executable file is also provided for download at http://www.siuc.edu/~epse1/sheng/Fortran/MUIRT/EXAMPLE.zip to demonstrate the implementation of the algorithm on simulated data.

Markov Modeling Of Breast Cancer, Chunling Cong, Chris P. Tsokos

Journal of Modern Applied Statistical Methods

Previous work with respect to the treatments and relapse time for breast cancer patients is extended by applying a Markov chain to model three different types of breast cancer patients: alive without ever having relapse, alive with relapse, and deceased. It is shown that combined treatment of tamoxifen and radiation is more effective than single treatment of tamoxifen in preventing the recurrence of breast cancer. However, if the patient has already relapsed from breast cancer, single treatment of tamoxifen would be more appropriate with respect to survival time after relapse. Transition probabilities between three stages during different time periods, 2-year, …

Data Note: Job Seekers With Disabilities At One-Stop Career Centers: An Examination Of Registration For Wagner-Peyser Funded Employment Services From 2002 To 2007, David Hoff, Frank A. Smith

Data Note Series, Institute for Community Inclusion

The Wagner-Peyser Act of 1933 established a nationwide system of public employment services, known as the Employment Service. Wagner-Peyser funds are a primary source of funding for the services of One-Stop Career Centers that provide employment services available to all people, including people with disabilities. This data note examines trends on a national and state-by-state basis in the number and percentage of job seekers who self-identified as having disabilities who register for Wagner-Peyser Employment Services.

Between A Rock And A Soft Place: Ecological And Feminist Economics In Policy Debates, Julie A. Nelson

Economics Faculty Publication Series

The field of ecological economics includes both economic analysis on the one hand, and discussions of normative values and visions for society, on the other. Using feminist insights into cultural beliefs about the relative “hardness” and “softness” of these two sides, this essay discusses how ecological economists can use this unique “between” space in order to better inform policy. The current crisis of global climate change, it is argued, requires that economists move beyond modeling and measurement, while ecological thinkers need to re-examine beliefs about markets and profit.

Impact Of Rank-Based Normalizing Transformations On The Accuracy Of Test Scores, Shira R. Soloman, Shlomo S. Sawilowsky

Journal of Modern Applied Statistical Methods

The purpose of this article is to provide an empirical comparison of rank-based normalization methods for standardized test scores. A series of Monte Carlo simulations were performed to compare the Blom, Tukey, Van der Waerden and Rankit approximations in terms of achieving the T score’s specified mean and standard deviation and unit normal skewness and kurtosis. All four normalization methods were accurate on the mean but were variably inaccurate on the standard deviation. Overall, deviation from the target moments was pronounced for the even moments but slight for the odd moments. Rankit emerged as the most accurate method among all …

Bayesian Analysis Of Evidence From Studies Of Warfarin V Aspirin For Symptomatic Intracranial Stenosis, Vicki Hertzberg, Barney Stern, Karen Johnston

Journal of Modern Applied Statistical Methods

Bayesian analyses of symptomatic intracranial stenosis studies were conducted to compare the benefits of long-term therapy with warfarin to aspirin. The synthesis of evidence of effect from previous nonrandomized studies in monitoring a randomized clinical trial was of particular interest. Sequential Bayesian learning analysis was conducted and Bayesian hierarchical random effects models were used to incorporate variability between studies. The posterior point estimates for the risk rate ratio (RRR) were similar between analyses, although the interval estimates resulting from the hierarchical analyses are larger than the corresponding Bayesian learning analyses. This demonstrated the difference between these methods in accounting for …

A Maximum Test For The Analysis Of Ordered Categorical Data, Markus Neuhäeuser

Journal of Modern Applied Statistical Methods

Different scoring schemes are possible when performing exact tests using scores on ordered categorical data. The standard scheme is based on integer scores, but non-integer scores were proposed to increase power (Ivanova & Berger, 2001). However, different non-integer scores exist and the question arises as to which of the non-integer schemes should be chosen. To solve this problem, a maximum test is proposed. To be precise, the maximum of the competing statistics is used as the new test statistic, rather than arbitrarily choosing one single test statistic.

Social Science In A Water Observing System, John B. Braden, Daniel G. Brown, Jeff Dozier, Patricia Gober, Sara M. Hughes, David R. Maidment, Sandra L. Schneider, P. Wesley Schultz, James S. Shortle, Stephen K. Swallow, Carol M. Werner

Psychology Faculty Publications

We set forth an argument for the integration of social science research with natural science and engineering research in major research infrastructure investments addressing water science. A program of integrated observation of water resources offers great opportunities to address several environmental “grand challenges” identified by the National Research Council, including climate variability, institutions and resource use, and land use dynamics, and their importance for hydrologic forecasting. We argue that such a program has the potential to advance both water science and the contributing disciplines. However, to realize this potential, it is essential to recognize that social science requires critical infrastructure …

The Effective Target Of The Social Security Disability Benefits Reform Act Of 1984, Perry Douglas Singleton

Center for Policy Research

A substantial portion of the rise in Social Security Disability Insurance rolls since 1984 has been attributed to the Social Security Disability Benefits Reform Act. Using data from the National Health Insurance Survey, I examine whom the act effectively targeted. The analysis shows that new enrollees were demonstrably taller than previous enrollees, suggesting that the act expanded eligibility to individuals in better health and socioeconomic circumstances. However, the estimated effect of increased SSDI eligibility on employment is low, suggesting that the act targeted males who would have otherwise been unemployed.

Path To Financial Inclusion: The Success Of Self-Help Groups-Bank Linkage Program In India, Sivakumar Venkataramany, Balbir B. Bhasin

WCBT Faculty Publications

Financial inclusion has been a major theme in both industrialized and developing economies in the era of financial globalization. When microcredit institutions have received limited success in many countries, microfinance is being used in India for the purpose of accomplishing universal financial inclusion. This paper recognizes the overwhelming efforts of the Government of India and focuses on the success of the linkage between commercial banks and self-help groups (SHGs). The SHGs comprising predominantly women groups help in the social cause of alleviation of poverty, increase of sustainability, reduction of vulnerability, improvement of capacity building and help the weaker sections build …

Cinematherapy With Preadolescents Experiencing Parental Divorce: A Collective Case Study, Emily Marsick

Expressive Therapies Dissertations

A multiple-case study of the use of cinematherapy in six sessions of individual therapy each with three preadolescent aged children who were experiencing parental divorce was conducted. Children were shown film clips from six different films over six weeks of individual therapy. Questions were used to facilitate discussion with the children and children were given the opportunity to respond to the film clips expressively, by using their choice of art, creative writing, story-telling, and/or drama. Each child was interviewed one to two weeks after the intervention. Multiple themes emerged across the cases, including the use of films for: assessment of …

Nebraska Immigration: Deliberative Polling And Civic Engagement On Broadcast And New Media Coverage, Jeremy Harris Lipschultz, Michael L. Hilt, David C. Ogden, Hugh J. Reilly

Communication Faculty Publications

Data were analyzed from an October 2007 deliberative poll event in Omaha, Nebraska. The focus of pre-event survey questions was on the usefulness of media sources on the coverage of the global immigration issue. The goal of the project was to promote civic engagement of citizens on an important public issue. The focus of post-event survey questions was on attention paid to media. Additionally, a post-event focus group explored public opinion on credibility of various news sources. While the deliberative poll produced some evidence of short-term effects in terms of citizens learning about the immigration issue, attitudes about media credibility …

Extinguishing The Torch Of Terror: The Threat Of Terrorism And The 2010 Olympics, Serge E. Vidalis

Journal of Strategic Security

With the change in seasons comes the expected change of insurgency operations in Afghanistan as Taliban and al-Qaida fighters mount their spring and summer offensives against both NATO forces and Afghanis sympathetic to foreign troops. As insurgents curtail their seasonal operations with the arrival of fall and winter, is it likely that a threat may arise from Afghanistan to affect the 2010 Olympics in Vancouver, British Columbia? As will be illustrated herein, the threat to the games will not be borne directly from the insurgency in Afghanistan but rather by the universal jihadist ideology of al-Qaida rather than the nationalist …
