An Economic Analysis of Secure Messaging between Patients and Providers
… To answer this question, a cost minimizing model is estimated. An instrumental variable approach was used to correct for the potential correlation of health and secure messaging user measures with the error term. A potential problem of unobserved individual heterogeneity was also taken into …

New Multivariate Zero-Inflated Beta-Binomial Distribution
The multivariate zero-inflated beta-binomial model is significantly important for modelling and analyzing multivariate proportional data with extra zeros. Comparing with the binomial model, the beta-binomial model is a better alternative for explicitly accounting for over-dispersion, and …

The economics of military spending, conflict and growth
… and non-linearity. Using an exogenous growth model and dynamic panel approach, the results suggest military burden to have a negative effect on growth. Breaking the overall panel down into various sub-samples shows estimates that are remark-ably consistent with the full panel. These results …

A Simulation Study to Evaluate Bayesian LASSO’s Performance in Zero-Inflated Poisson (ZIP) Models
When modelling count data, it is possible to have excessive zeros in the data in many applications. My thesis concentrates on the variable selection in zero-inflated Poisson (ZIP) models. This thesis work is motivated by Brown et al. (2015), who considered the excessive amount of zero in their data …

Predicting earthquake casualty rates accounting for community vulnerability
… analyses regarding future earthquakes. Existing models for predicting earthquake casualties, however, had three general limitations. They usually required a detailed building inventory that might not be readily available. They tend to account insufficiently for socioeconomic factors that may …
