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
(2012)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. ... -
Considerations on the UK re-arrest hazard rate analysis
(2011)The offence risk posed by individuals who are arrested, but where subsequently no charge or cau- tion is administered, has been used as an argument for justifying the retention of such individuals? DNA and identification ... -
Dependent Gaussian mixture models for source separation
(2012)Source separation is a common task in signal processing and is often analogous to factor analysis. In this study, we look at a factor analysis model for source separation of multi-spectral image data where prior information ... -
Squaring the Circle? Work and Family Issues among Owners of Small Business
(ISBE, 2010-11)This paper addresses the largely under-researched theme of how entrepreneurs in Ireland manage their business lives in parallel with their family commitments, with specific reference to dependent children. Since the ... -
Estimating production test properties from test measurement data
(Wiley-Blackwell, 2011)A complex sequence of tests on components and the system is a part of many manufacturing processes. Statistical imperfect test and repair models can be used to derive the properties of such test sequences but require model ... -
Nonparametric Predictive Utility Inference
(Elsevier, 2012)We consider the natural combination of two strands of recent statistical research, i.e., that of decision making with uncertain utility and that of Nonparametric Predictive Inference (NPI). In doing so we present the idea ... -
Bayesian Calibration of a Natural History Model with Application to a Population Model for Colorectal Cancer
(2011)Background. Cancer natural history models are essential when evaluating screening/preventative interventions or changes to diagnostic pathways. Natural history models commonly use a state transition structure, but it is ... -
Calibration of cosmogenic 36Cl production rates from Ca and K spallation in lava flows from Mt. Etna (38?N, Italy) and Payun Matru (36?S, Argentina)
(2011)Published cosmogenic 36Cl production rates from Ca and K spallation differ by almost a factor of 2. In this paper we determine production rates of 36Cl from Ca and K in samples of known age containing little Cl. Ca-rich ... -
Who's Minding the Kids? Work and Family Issues among Owners of Small Business Enterprises in Ireland
(Edward Elgar, 2011)This chapter addresses the largely under-researched theme of how entrepreneurs in Ireland manage their business lives in parallel with their family commitments, with specific reference to dependent children. Since ... -
Rate of familial amyotrophic lateral sclerosis: a systematic review and meta-analysis.
(2011)Background The population rate of familial amyotrophic lateral sclerosis (FALS) is frequently reported as 10%. However, a systematic review and meta-analysis of the true population based frequency of FALS has never been ... -
Workshop on Machine Learning Techniques for Processing Multimedia Content
(2005)Machine Learning (ML) techniques are used in situations where data is available in electronic format and ML algorithms can ?add value? by analysing this data. This is the situation with the processing of multimedia ...
