Sampling for conditional inference on contingency tables, multigraphs, and high dimensional tables
… importance sampling methods for sampling contingency tables with fixed margins, loopless, undirected multigraphs, and high-dimensional tables. In each case, the proposals for the method are constructed by leveraging approximations to the total number of structures (tables, multigraphs, or …

Empirical Bayes estimators for the cross-product ratio of 2x2 contingency tables
… of sampling distributions of cell counts of 2x2 contingency tables were considered. In the Independent Poisson Case, an empirical Bayes estimator for the cross-product ratio is presented. If the squared error loss function is used, this empirical Bayes estimator, ᾶ, has asymptotic risk only ε > 0 …

Structural Equation Modeling of Binary Preference Data
… a family of statistics for testing sparse binary contingency tables under multinomial sampling is proposed. These statistics are used to assess the goodness of fit of Thurstonian models for binary preference data.

Explicit Estimates for Cell Counts and Modeling The Missing Data Indicators in Three-Way Contingency Table by Log-Linear Models
… log-linear models. Model based approach for contingency tables has the advantage of providing the information of missing data mechanisms. Previous methods for contingency tables with supplementary margins required an iterative algorithm, however, expected cell counts for complete cells as …

Horizontal starch gel electrophoresis as a technique for examining gray squirrel population genetics
… compared among several woodlots using chi-square contingency tables. On the basis of these frequencies, no differences were found among the woodlot populations of gray squirrels examined in this study.

Analyzing capital expenditure in commercial real estate assets
… and capital expenditure. The thesis uses contingency tables to understand the behavior of commercial properties over a span of nine years. The goal was to understand if capital expenditure spends have an impact on future spends. If an investor invests high (low) capital expenditure in the …

Job Satisfaction and Dissatisfaction Factors of Airport Security Screeners: National Survey Results
… The results were analyzed using chi-square contingency tables, one-way analysis of variance tests, and the Fisher post-hoc procedure. Post-hoc comparisons were also analyzed between demographic groups, as well as between the upper and lower quartiles of security screener job experience …

Real estate opportunity funds : past fund performance as an indicator of subsequent fund performance
… include regression analysis, construction of contingency tables, and calculation of rank correlation coefficients. Tests were based on return data from the period 1991 to 2001 and were similar to those used to analyze performance persistence in other investment vehicles such as mutual funds …

The Joint Influence of ENSO and NAO on US Landfalling Hurricanes and their Origination Points
Contingency tables were utilized in order to characterize the relationship between the El Niño Southern Oscillation (ENSO) and the North Atlantic Oscillation (NAO). Global atmospheric anomalies were then examined in addition to hurricane landfall and origination locations (i.e., the position …

Effects of Students' multiple Intelligences on Participation Rate of Course Components in a Blended Secondary Family and Consumer Sciences Course
… with descriptive analysis, ANOVA testing, and contingency tables. Howard Gardner's multiple intelligence inventory was used to determine students' learning styles. The learning styles were compared with the participation rate of four course components: individual assignments, group projects, …

The use of correspondence analysis in building loglinear models
… set out in the form of (multi-dimensional) contingency tables, is usually subjected to hypothesis testing in order to assess the interrelationships between the questions. Prior to undertaking confirmatory procedures, we argue that exploratory techniques should be used to gain a "feel" for …

Sequential analysis of categorical data
… commonly used in goodness-of-fit tests, contingency tables, and Mood's non-parametric generalization of the one-way analysis of variance, (ii) calculation or a power function, and (iii) calculation of the greatest expected ASR's and the non-centrality parameter requiring this sample size …

Modeling and Measuring Association for Ordinal Data
… statistic and consider it in the cumulative contingency tables. For the non-cumulative tables, we provide the scoring systems and the variance minimization correction term to Pearson goodness-of-fit statistic. We also put forward the average of individual odds ratios as the common odds ratio …

Survivorship bias in mutual fund performance : evidence in Canadian mutual funds
… funds, and later on funds in all categories. Contingency tables are used to address the question of performance persistence. Cross Product Ratios (CPR) are obtained for all funds, active and inactive, on an annual basis. Probit models are used to explore the odds of and factors that contribute …

Multi-source contingency clustering
… in the form of normalized multidimensional contingency tables in order to recover robust mappings between data points and clusters for each of the individual data sources. We outline a unifying formalism by which one might approach cross-channel clustering problems, and begin by defining an …

Supportive Measures: An Analysis of the TRIO Program - Student Support Services at East Tennessee State University from 2001 – 2004
… using one-way analysis of variance, two-way contingency tables, multivariate linear regressions, and binary logistic regressions. Results indicated that there were significant differences in demographic and performance outcomes among the 3 study groups. SSS participants were found to have a …

Variation in Computerized Tomography Scan Utilization
… variation on CT scan usage in New York State. Contingency tables were developed to evaluate to what extent patient and hospital characteristics contribute to the variation. A logistic regression model was built to control the variation caused by patient and hospital characteristics in order to …
