An aid to intuitively understanding bias and consistency
Spencer, Neil (1999)Students often find the concepts of bias and consistency hard to understand intuitively. This paper presents means of demonstrating these concepts using a computer so that the students, once they have seen them in action, ... -
The Analyses of Individual Patient Pathways : Investigating Regional Variation in COPD readmissions
Adeyemi, Shola; Demir, Eren; Chaussalet, Thierry J (Vilnius Gediminas Technical University Publishing House “Technika”, 2009-07-13)Regional variation for those treated for chronic obstructive pulmonary disease (COPD) has been studied amongst many public health issues.

An approach to exploring the effect of weather variations on chronic disease incidence rate and potential changes in future health systems
Demir, Eren (Institute of Electrical and Electronics Engineers (IEEE), 2010)The ecology and the environment of the world are changing due to the changing patterns of the meteorological factors. Scientific recognition confirms that such variation have already started affecting health and disease ... -

(2023-12-28)In recent years, there has been a surge in the global digitization of corporate processes and concepts such as digital technology development which is growing at such a quick pace that the construction industry is struggling ... -
Assessing bias in online surveys using alternative survey modes
Spencer, Neil; Syrdal, Dag Sverre; Coates, Matthew; Huws, Ursula (2022-05-14)Due to concerns that respondents to online surveys are different from populations of interest, parallel offline surveys can be undertaken and results compared. In this article we create a set of principles to compare results ... -
Assessing the impact of COVID-19 measures on COPD management and patients: A simulation-based decision support tool for COPD services in the UK
Yakutcan, Usame; Hurst, John R.; Lebcir, Reda M.; Demir, Eren (2022-10-07)Objectives To develop a computer-based decision support tool (DST) for key decision makers to safely explore the impact on chronic obstructive pulmonary disease (COPD) care of service changes driven by restrictions to ... -
Association Between Experiencing Relational Bullying and Adolescent Health Related Quality of Life
Chester, Kayleigh; Spencer, Neil; Whiting, Lisa; Brooks, Fiona (2017-11-01)BACKGROUND Bullying is a public health concern for the school-aged population, however, the health outcomes associated with the subtype of relational bullying are less understood. The purpose of this study was to examine ... -
Associations between physical activity in adolescence and health behaviours, well-being, family and social relations.
Brooks, F.; Smeeton, N.C.; Chester, Kayleigh; Spencer, Neil; Klemera, Ellen (2014-09-16)Across Europe and North America, few young people meet the recommended levels of physical activity (PA) of 1 hour of moderate to vigorous PA per day. However, the lives of young people cannot simply be polarised as either ... -
An automatic-democratic approach to weight setting for the new human development index
Tofallis, C. (University of Hertfordshire, 2012)Perhaps the most difficult aspect of constructing a multi-dimensional index is that of choosing weights for the components. This problem is often bypassed by adopting the ‘agnostic’ option of equal weights, as in the Human ... -

A better measure of relative prediction accuracy for model selection and model estimation
Tofallis, C. (2015-08-01)Surveys show that the mean absolute percentage error (MAPE) is the most widely used measure of forecast accuracy in businesses and organizations. It is however, biased: When used to select among competing prediction methods ... -
Can medical humanities impart empathy and resilience skills to medical students?
Berman, Hayley; Schamroth, Alan; Spencer, Neil (2020-10-06)The contribution of the Medical Humanities to a comprehensive medical education has been discussed elsewhere (Schamroth A. 2018), but what has been difficult to demonstrate is whether it has any measurable quantitative ... -
Capturing the readmission process : the focus on the time window
Demir, Eren; Chaussalet, Thierry J (2011)In the majority of studies on patient re-admissions, a re-admission is deemed to have occurred if a patient is admitted within a time window of the previous discharge date. However, these time windows have rarely been ... -

A Comparison of Modelling Strategies for Value-Added Analyses of Educational Data
Spencer, Neil; Fielding, A. (University of Hertfordshire, 2000)Modelling strategies for value-added multilevel models are examined. These types of models typically include an endogenous variable and this causes difficulties for the standard estimation techniques that are commonly used ...
