Conditional Visualisation for Statistical Models
It is difficult to understand data and statistical models in high-dimensional space. One way to approach the problem is conditional visualisation, but methods in this area have lagged behind the considerable advances in statistical modelling in recent decades. This thesis presents a new approach to …

Statistical models with diverging dimensionality
Nowadays in many statistical applications, we face models whose complexity increases with the sample size. Such models pose a challenge to the traditional statistical analysis, and call for new methodologies and new asymptotic studies, which are exactly the focus of my thesis. In particular, my …

Statistical models with dichotomous response
Statistical models with dichotomous response are investigated. Many techniques for modeling such situations are discussed which involve various types of distributions. The two distributions which shall be discussed further are those related to probit and logit analysis. Several estimation methods …

STATISTICAL MODELS UTILIZING DEPENDENCE BETWEEN VARIABLES
… Maximum likelihood estimation in log-linear models for multinomial distributions is equivalent to solving an <italic>I<italic>-projection problem (Robertson et. al, 1988). I-projection and Fenchel's duality were used in our research to introduce the proposed model. We consider estimating the …

Statistical models for extreme weather events
… associated with these phenomena is minimised. In statistical modelling, extreme value analysis is typically used to model the rate and size of extreme weather events. Typically, practitioners can use the outputs of such an analysis to design flood defences to a standard such that there is only a …

Statistical models in medical image analysis
… of simple image processing routines. Statistical models provide application-specific context to the problem by incorporating information derived from a training set consisting of instances of the problem along with the solution. In this thesis, we explore the benefits of statistical …

Tropical Cyclone Risk Assessment Using Statistical Models
… cost of running TC-permitting dynamical models indicate a need for statistical models that can simulate large ensembles of TCs in order to cover the full range of possible activity that results from a given climate change. I construct and apply a statistical track model from the 1945-2007 …

Statistical models and inference for dynamic networks
Dyadic data are ubiquitous and arise in the fields of biology, epidemiology, sociology, and many more. Such dyadic data are often best understood within the framework of networks. Network data can vary in many ways. For example, one might have binary or weighted networks, directed or undirected …

Statistical models for noise-robust speech recognition
A standard way of improving the robustness of speech recognition systems to noise is model compensation. This replaces a speech recogniser's distributions over clean speech by ones over noise-corrupted speech. For each clean speech component, model compensation techniques usually approximate the …

Statistical Models for Extreme Events in Atmospheric Processes
… and energy budgets. However, characterizing the statistical properties of such events is a challenging task, as (i) by definition extremes are poorly sampled, and thus studying them often requires extrapolation beyond the range of available observations, and (ii) extremes are often the result of …

Atomic -Scale Statistical Models of Semiconductor Device *Reliability
We have developed a detailed model for hot-carrier induced interface state generation in silicon metal-oxide semiconductor field-effect transistors (MOSFETs). In the process, we discuss a different interpretation of the isotope effect of silicon-hydrogen (deuterium) bond dissociation by electronic …

STATISTICAL MODELS AND INFERENCE FOR LI-ION BATTERY PROGNOSTICS

Statistical models for dependent and non-stationary extreme events

Many statistical models and methods of inference exist for the extreme values of univariate sequences of independent and identically distributed (IID) random variables. However, in most applications, the data sets are not IID and are often multivariate, …

Statistical models of claim amount distributions in general insurance
This work examines the following statistical distributions as possible models for the distribution of claim amounts in general insurance: 1- The lognormal 2- The Weibull 3- The inverse Gaussian (A new 3-parameter form is introduced) 4- The Pareto 5- The truncated lognormal as a model for large …
