Factors influencing when species are first named and estimating global species richness
(2015)Estimates of global species richness should consider what factors influence the rate of species discovery at global scales. However, past studies only considered regional scales and/or samples representing <0.4% of all ... -
Exponential family mixed membership models for soft?clustering of multivariate data
(2016)For several years, model-based clustering methods have successfully tackled many of the challenges presented by data-analysts. However, as the scope of data analysis has evolved, some problems may be beyond the standard ... -
The effects of Flare Definitions on the Statistics of Derived Flare Distributions.
(2016)The statistical examination of solar flares is crucial to revealing their global characteristics and behaviour. Such examinations can tackle large-scale science questions or give context to detailed single-event studies. ... -
Brain activity detection by estimating the signal-to-noise ratio of fMRI time series using dynamic linear models
(2015)This work shows an example of the application of Bayesian dynamic linear models in fMRI analysis. Estimating the error variances of such a model, we are able to obtain samples from the posterior distribution of the ... -

Mixed membership of experts stochastic blockmodel
(2016)Social network analysis is the study of how links between a set of actors are formed. Typically, it is believed that links are formed in a structured manner, which may be due to, for example, political or material ... -
Using resource modelling to inform decision making and service planning: The case of colorectal cancer screening in Ireland
(2013)Background Organised colorectal cancer screening is likely to be cost-effective, but cost-effectiveness results alone may not help policy makers to make decisions about programme feasibility or service providers to plan ... -

Bayesian inference for reliability of systems and networks using the survival signature
(2014)The concept of survival signature has recently been introduced as an alternative to the signature for reliability quantifcation of systems. While these two concepts are closely related for systems consisting of a single ... -
Using Storm for scaleable sequential statistical inference
(2014)This article describes Storm, an environment for doing streaming data analysis. Two examples of sequential data analysis | computation of a running summary statistic and sequential updating of a posterior distribution | ... -
The Impact of a Revised EQ-5D Population Scoring on Preference-Based Utility Scores in an Inflammatory Arthritis Cohort
(2011)Background and Objective It is well established that there are problems with the EQ-5D. This is due to the original scoring methods used and how negative time trade-off (TTO) values were treated. A revised scoring method ... -
Considerations on the UK Re-Arrest Hazard Data Analysis (How Model Selection Can Alter Conclusions for Policy Development)
(2011)The offence risk posed by individuals who are arrested, but where subsequently no charge or caution is administered, has been used as an argument for justifying the retention of such individuals? DNA and identification ... -
Bayesian spatiotemporal model of fMRI data using transfer functions
(2010)This research describes a new Bayesian spatiotemporal model to analyse BOLD fMRI studies. In the temporal dimension, we describe the shape of the hemodynamic response function (HRF) with a transfer function model. In ... -
Predicting the number of known and unknown species in European seas using rates of description
(2011)Aim? In this paper, we compare species description rates to predict the numbers of undescribed species. These data are used to discuss the merits of various attempts to estimate species richness in the oceans. Location? ... -
Short-term traffic flow forecasting with A-SVARMA
(2013)Short-term Traffic Flow Forecasting (STFF), the process of predicting future traffic conditions based on historical and real-time observations, is an essential aspect of Intelligent Transportation Systems (ITS). The existing ... -
A probability model of system downtime with implications for optimal warranty design
(2009)Traditional approaches to modeling the availability of a system often do not formally take into account uncertainty over the parameter values of the model. Such models are then frequently criticised because the ... -
The magnitude of global marine species diversity
(2012)Background The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register of the marine species ... -
Bayesian kernel projections for classification of high dimensional data
(2011)A Bayesian multi-category kernel classification method is proposed. The algorithm performs the classification of the projections of the data to the principal axes of the feature space. The advantage of this approach is ... -
Predicting total global species richness using rates of species description and estimates of taxonomic effort
(2012)We found that trends in the rate of description of 580,000 marine and terrestrial species, in the taxonomically authoritative World Register of Marine Species and Catalogue of Life databases, were similar until the 1950s. ...
