Extended Poisson Models for Count Data With Inflated Frequencies
… papers in the literature that show how to fit Poisson regression models that account for the zero inflation. However, in many situations the frequencies of zero and of some other value <em>k</em> tends to be higher than the Poisson model can fit appropriately. Recently, Sheth-Chandra (2011), …

Essays on the Bayesian inequality restricted estimation
… on the qualitative dependent variable models. Two Markov Chain Monte Carlo (MCMC) methods have been used throughout this dissertation to facilitate Bayesian estimation, namely Gibbs (1984) sampling and the Metropolis (1953, 1970) Algorithm. In this research, several Monte Carlo …

Periodicity and ruin probabilities for compound non-homogeneous poisson processes
Compound non-homogenous Poisson processes with periodic claim intensity rates are studied in this work. A risk process related to a short term periodic environment and the periodicity for its compound claim counting process are discussed. The ruin probabilities of compound non-homogenous Poisson …

Ahead of the Storm: Implications of Changing Parameters in U.S. Tropical Cyclone Likelihood and Damage Estimation Models in the Face of Global Climate Change
… two time periods in the United States. We fit Poisson models to U.S. tropical cyclone frequency data from a pre-climate change era to a post-climate change era and test equality of the Poisson rate parameters from each period to analyze changes in tropical cyclone frequency. We fit lognormal …

An Investigation of Answer Changing on a Large-Scale Computer-Based Educational Assessment
… and answer-changing variables were modeled using Poisson and negative binomial regression approaches. Results were consistent with prior research that has indicated large numbers of answer changes are rare occurrences that could warrant further exploration. Negative binomial regression was a …

On Development and Performance Evaluation of Some Biosurveillance Methods
… to detect a wide range of shifts in the mean of Poisson distributed biosurveillance data. The application of a sign function on the original GLR chart statistics leads to downward-sided, upward-sided, and two-sided GLR chart statistics in an unified framework. To facilitate the use of such charts …

Essays on the dynamics of qualitative aspects of firms' behavior
… different techniques are employed, which include Poisson models, structural form models and duration models. Our findings show that observable characteristics of the individual firms are important in understanding the dynamics of firm's attrition. Cyclical effects and macroeconomic variables have …

Measuring the Effects of Air Pollution among Persons with Severe Emphysema: The National Emphysema Treatment Trial (NETT)
… interpolated with the use of log-normal kriged models. This methodology was employed in order to assign exposures in areas with few nearby air pollution monitors. We investigated whether there was evidence of differential air pollution exposure by individual and area-level measures of …

Labour Market and Non-labour Market Outcomes of Education in Bangladesh: Does Education Matter in the Formation of Outcomes in Adulthood?
… approaches such as Ordinary Least Squares, Logit models, Propensity Score Matching and Poisson models. In the case of the investigation of labour market outcomes across educational routes, this thesis finds that an individuals’ educational route being either general or madrasah does affect an …
