Description
It is common in the analysis of data to provide a goodness-of-fit test to assess the performance of a model. In the analysis of contingency tables, goodness-of-fit statistics are frequently employed when modeling social science, educational or psychological data where the interest is often directed at investigating the association among multi-categorical variables. Pearson's chi-squared statistic is well-known in goodness-of-fit testing, but it is sometimes considered to produce an omnibus test as it gives little guidance to the source of poor fit once the null hypothesis is rejected. However, its components can provide powerful directional tests. In this dissertation, orthogonal components are used to develop goodness-of-fit tests for models fit to the counts obtained from the cross-classification of multi-category dependent variables. Ordinal categories are assumed. Orthogonal components defined on marginals are obtained when analyzing multi-dimensional contingency tables through the use of the QR decomposition. A subset of these orthogonal components can be used to construct limited-information tests that allow one to identify the source of lack-of-fit and provide an increase in power compared to Pearson's test. These tests can address the adverse effects presented when data are sparse. The tests rely on the set of first- and second-order marginals jointly, the set of second-order marginals only, and the random forest method, a popular algorithm for modeling large complex data sets. The performance of these tests is compared to the likelihood ratio test as well as to tests based on orthogonal polynomial components. The derived goodness-of-fit tests are evaluated with studies for detecting two- and three-way associations that are not accounted for by a categorical variable factor model with a single latent variable. In addition the tests are used to investigate the case when the model misspecification involves parameter constraints for large and sparse contingency tables. The methodology proposed here is applied to data from the 38th round of the State Survey conducted by the Institute for Public Policy and Michigan State University Social Research (2005) . The results illustrate the use of the proposed techniques in the context of a sparse data set.

Description
This expository thesis explores the financial health and actuarial analysis of a particular solution for those seeking stability and security in their golden years: the CCRC industry. A continuing care retirement community, or CCRC, is a comprehensive project and campus that offers its residents a full spectrum of care from independent living, to assisted living, to skilled nursing. After reading this paper, any person with no prior knowledge of a continuing care retirement community should gain a firm understanding of the background, risks and benefits, and legislative safeguards of this complex industry. Financially, a CCRC operates in some aspects similar to long-term care (LTC) insurance. However, CCRCs provide multiple levels of care operations while maintaining a pleasant, engaging community environment where seniors can have all their lifestyle needs met. The expensive and complex operations of a CCRC are not without risk: the industry has seen marked periods of bankruptcy followed by increasing and changing regulatory oversight. Thus, CCRCs require a periodic actuarial analysis and report, among array of other legislative safeguards against bankruptcy. A CCRC's insolvency or inability to meet its obligations can be catastrophic and inflict suffering and damages not only to its residents but also their friends and families. With seniors historically being one of the most vulnerable demographic groups, it is absolutely essential that an all-encompassing care facility continues to exist and fulfill its contractual promises by maintaining sound actuarial practices and financial health. This thesis, in addition to providing an exposition of the background and functions of the CCRC, describes the existing actuarial and financial studies and audits in practice to ensure sound governance and the quality of life of CCRC residents.

What is a “Good Economy”? Analysis of Economic Metrics & Their Political Impact on the United States
Description
The goal of this research paper is to analyze how we define economic success and how that affects large corporations and consumers. This paper asks the questions: What do we define as a good economy? What metrics are currently utilized? And how do perceptions of a good economy influence politics? Overall, the research seeks to identify common economic and financial fallacies held by the average citizen and offer alternative methods of how socio-economic information is presented to the consumers. Consumers play a major role in the market, and the information they receive has a considerable impact on their behaviors. Determining why the present economic analysis is used is the first step in finding ways to improve the system. Observing past political and economic trends and relating them to current issues is necessary for finding future solutions.
