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 ...

This research study investigated student performance in mathematics during the transition from primary to post-primary school. Academic achievement in mathematics was measured using a standardised test at the end of sixth ...

The spreading of behavior, such as the adoption of a new innovation, is influenced by the structure of social networks that interconnect the population. In the experiments of Centola [15], adoption of new behavior was shown ...

Solar-thermal collectors capture solar energy and convert it into heat energy. Several types of solar-thermal collectors have been used to harness solar radiation in both residential, electricity generation, and industrial ...
