Examining measles, mumps, and rubella (MMR) immunization uptake in Saskatoon: Can neighbourhood characteristics predict coverage rates?
… in Canada yet continuous monitoring of coverage rates is essential to ensure high uptake and the continued success of these programs. Prior to this study, Saskatoon Public Health Services (PHS) were limited to manual calculation of coverage rates and trends and were unable to examine …

Investigation of bootstrap estimates of the parameters, their standard errors, and associated confidence intervals of structural equation models with ordered categorical variables
… estimates, their standard errors and the coverage rates of the associated bootstrap confidence intervals. Structural equation models are used widely in many disciplines and often the data analyzed involve ordered categorical variables. The performance of the bootstrap has been investigated …

Inference for the ratio of two exponential parameters using a Bayesian approach
… will be compared with each other in terms of coverage rates and average interval lengths. It seems that if inference is made on the ratio of two exponential parameters, the Jeffreys prior performs better in terms of coverage rates, but the maximal data information prior performs better in …

Statistical methods for random rotations
… in the literature, but they have undesirable coverage rates for small samples. In Chapter 3 we propose a nonparametric pivotal bootstrap to calibrate confidence regions for the central orientation. We demonstrate the benefits of using calibrated confidence regions in a simulation study and …

Selecting an Optimal Measurement Model and Detecting Differential Item Functioning Using Bayesian Confirmatory Factor Analysis
… model. I compared the power and Type I error rates for DIF detection across conditions, and assessed the quality of estimates by calculating bias and 95% CI coverage rates for key parameters. Results indicate that although WAIC has less sampling variability than DIC, their model preferences …

Advances in Survival Analysis: Accurate Partial Likelihood Computation by Poisson-Binomial Distributions and Nonparametric Competing Risk Cox Model
… error while improving confidence interval coverage rates, particularly when ties are frequent or risk score variability is high. The second project develops a nonparametric regression model for competing risks survival data by combining the proportional cause-specific hazards framework with …

The Impact of Sample Size, Prevalence, Estimation Method and Other Factors When Estimating Multilevel Logistic Models
… of statistical power, confidence interval coverage and width, and likelihood of non-positive definite G-matrices, other key features of multilevel models including the level of random intercept and slope variance and estimation method also impact results. Greater levels of intercept and …

Essays on Economic Policy: Income Inequality and Health Insurance
… In steady state, differences in household saving rates generate differences in household capital income. Households that save more accumulate more capital and have higher steady-state income. Tax policy affects the distribution of income through its influence on household saving rates. Increasing …
