Statistical Challenges in the Modelling and Analysis of Critical Care Mortality Data
… in hospital intensive care units (ICUs). Patient mortality in hospital is the outcome that is monitored, and the standardised mortality ratio (SMR) is the performance indicator. Four inter-related methods of calculating SMRs are considered using a general multilevel model that contains patient- …

Modeling zero-inflated and overdispersed count data: application to in-hospital mortality data
… is associated with increased in-hospital mortality. Length of hospital stay (LOS) is often used as an indicator of hospital efficiency, a proxy of resource consumption and is especially important in organizing hospital services. Such data often have a highly right-skewed distribution for …

Characterising recent mortality trends in people with bipolar disorder and schizophrenia in England using linked hospital and mortality data
Background and objectives Mortality is higher in people with severe mental illness than others. An important policy goal is to reduce this ’mortality gap’. The objectives of this thesis were to investigate whether the gap has reduced in recent years in people with bipolar disorder or schizophrenia, …

The spatial and temporal anatomy of seasonal influenza in the United States, 1968-2008
… using monthly pneumonia and influenza (P and I) mortality to model inter-state movement of seasonal influenza in the continental United States between 1968 and 2008. The first chapter summarizes the current knowledge of the burden, morphology, and geography of influenza as well as limitations of …

Global mortality attributable to alcoholic cardiomyopathy
… registries provide valuable information of ACM mortality. However, for the majority of countries and global population, the cardiomyopathy burden attributable to alcohol consumption needs to estimated. Established methods for estimating alcohol-attributable fractions (AAF), i.e. proportion of an …

Some Advanced Semiparametric Single-index Modeling for Spatially-Temporally Correlated Data
… to develop two models for spatially correlated data; and the third is to further develop two models for spatially-temporally correlated data. To address the first topic, we propose a unified approach in its ability to simultaneously estimate the nonlinear relationship and change points. We …

Alternative estimation methods for survival models
… three parameter survival models for the force of mortality, the Makeham model and the Weibull model. The existing methods for estimating these parameters by the method of least-squares include using a log-transformation on the force of mortality data. We will propose another method of estimating …

The Contribution of Medical Measures to The Mortality Decline in England and Wales, New Zealand and Italy: An Age-Period-Cohort Model
The mortality decline in the more developed nations has been related to three factors: a reduction in exposure to disease, improved nutrition, and medical measures. The contribution of medical measures has been a source of continuing controversy. This contribution has been examined using one of two …

Array methods in statistics with applications to the modelling and forecasting of mortality
… arrays with particular reference to mortality data. A broad outline follows. We begin with an introduction to smoothing in one dimension, followed by a discussion of multi-dimensional smoothing methods. We then move on to review and develop the array methods of Currie et al. (2006), …

Cross resistance to organophosphorus compounds in malathion- and diazinon- resistant strains of the German cockroach
Dosage mortality data by a topical application method for eight organophosphorus compounds are given for two laboratory-selected .strains of Blattella p:ermanica ( L.), one resistant to malathion and the other resistant to diazinon. Comparison of this data with similar data for a normal susceptible …

Subnational Estimation of Period Child Mortality in a Low and Middle Income Countries Context
Child mortality is an important metric used in quantifying and monitoring the health of a population's children. Moreover, child mortality can be a key indicator of the overall health of a population, and is often used to quantify mortality at other ages. Over the past several decades, there have …
