In many evolutionary games, such as parental care games, the length of time spent playing a realisation of the game is dependent on the strategy of an individual. Also, the payoff of a deserting male cannot be defined ...

We develop a Smooth Lasso for sparse, high dimensional, contingency tables and compare its performance with the usual Lasso and with the now classical backwards elimination algorithm. In simulation, the usual Lasso had ...

Latent variable models have been used extensively in the social sciences. In this work a latent class analysis is used to identify syndromes within Alzheimer's disease. The fitting of the model is done in a Bayesian framework, ...

A single nucleotide polymorphism or SNP is a site of the genome where variation occurs within a population. Almost all SNPs have only two alleles (variants). In this work, we consider a statistical method based on a ...

When trading incurs proportional costs, leverage can scale an asset's return only up to a maximum multiple, which is sensitive to its volatility and liquidity. In a model with one safe and one risky asset, with constant ...

We study the inverse problem in Optical Tomography of determining the optical properties of a medium ⊂ Rn, with n ≥ 3, under the so-called diffusion approximation. We consider the time-harmonic case where is probed ...

The survival function of the logistic proportional hazards (PH) regression model, MacKenzie (1996), is obtained. A general likelihood for interval censored survival data which depends only on various closed forms of ...

Lower a posteriori error bounds obtained using the standard bubble function approach are reviewed in the context of anisotropic meshes. A numerical example is given that clearly demonstrates that the short-edge jump residual ...

Objectives Rates of burnout and stress in healthcare practitioners are steadily increasing. Emergency department (ED) staff are particularly susceptible to such poor outcomes. Mantra meditation (MM) may contribute to ...

In the first part of this thesis, mathematical models describing solvent and drug diffusion in glassy polymers are investigated using both numerical and approximate methods. These models are analysed using formal ...
