This paper demonstrates the use of spatial interaction models for international student migrant tablesusing a negative binomial regression in order to account for overdispersion. The Expectation-Maximization (EM) algorithm is used in fitting these models to account for missing cells, which
CASS is a programme of short courses covering topics in survey design, data collection and data analysis methods. Courses are aimed at academic social scientists and applied researchers in government, market research and the independent and voluntary sectors. Further information
Five reasons for measuring period fertility are distinguished: to describe fertility time trends, to explain these, to anticipate future population prospects, to provide input parameters for formal models, and to communicate with non-specialist audiences. The paper argues that not all
The Gini coefficient has proved valuable as a measure of income inequality. In cross-sectional studies of the Gini coefficient, information about the accuracy of its estimate is crucial. We show how to use jackknife and linearization to estimate the variance
When the aim of an experiment is the estimation of a Generalised Linear Model (GLM), standard designsfrom linear model theory may prove inadequate. This paper describes a flexible approach for findingdesigns for experiments to estimate GLMs through the use of
A simultaneous confidence band provides useful information on the plausible range of the unknown regression model. Construction of a simultaneous confidence band has a history going back to Working and Hotelling (1929) and is often a hard problem when the
Female genital cutting (FGC) is a widespread cultural practice in Africa, with a number of potential adverse health consequences for women. International organisations, national governments together with NGOs, community-based and grass-root organisations are trying to reduce the prevalence of FGC.
S3RI member James Raymer along with Frans Willekens has released his book concerning international migration in Europe. The book is ideal for academics and students with an interest in migration research and is also of benefit to statisticians responsible for
In this paper, we explore internal migration in England and Wales by broad groups of ethnicity, education and employment status from 1991 to 2004. The aim is to identify key differences in the patterns and trends over time so that
Giving by individuals for development has been illustrated recently by some spectacular examples. A few people giving very large sums, and a very large number of people giving modest amounts, are both important phenomena in the field of development finance.
Researchers in the Schhol of Mathematics, Southampton Statistical Research Institute (S3RI) and the School of Engineering Sciences at the University of Southampton have won a substantial EPSRC Bridging the Gaps grant to fund multidisciplinary research under the name Symbiosis (http://www.symbiosis.soton.ac.uk/).
Literature examining immigrants’ educational disadvantage across countries focuses generally on average differences in educational outcomes between immigrants and natives disguising thereby that immigrants are a highly heterogeneous group. The aim of this paper is to examine educational inequalities among immigrants
We consider the problem of finding an optimal design under a Poisson regression model with a log link, any number of independent variables and an additive linear predictor. Local D-optimality of a class of designs is established through use of
The Spring S3RI seminar will be given by Professor David Banks (Duke University, USA) on Statistical Issues in Metabolomics. Metabolomics is an emerging area of bioinformatics that uses measurements on metabolites in tissue samples to assess health status, evaluate drug
The economics of welfare is at the heart of economics, but in recent decades welfare economics has been relegated to the sidelines. While economists routinely make policy recommendations, or statements about economic success or failure, they often do so without
SSBS08) to be held from 27-29 August 2008 at Southampton University. The conference will be preceded by a 1.5 day short course. Full details are available on the conference website.
The predominant part of the literature states that women are more likely to donate to charitable causes but men are more generous in terms of the amount given. The latter result generally derives from the focus on mean amount given.
A meeting on Computer Experiments will be held at Southampton on 13 February 2008, jointly organised by the General Applications Section of the Royal Statistical Society and S3RI. Computer experiments refers to the design and analysis of experiments on complex
