The Department's renewal and refreshment proceeded successfully in 2000 resulting in a sizeable, healthy and vibrant Statistics group. In particular, Paul Garthwaite was appointed to the established Chair in Statistics and Pia Larsen, Catriona Queen and Karen Vines were appointed to Lectureships. In addition, Chris Jones was promoted to Professor of Statistical Science.
This appointment activity did not hinder Departmental productivity in terms of research or teaching. During 2000, Department members published 19 papers in refereed journals and 3 book chapters. We hold a Grade 4 rating from the 1996 Research Assessment Exercise, but personnel has changed significantly since then and the number of research-active staff has increased considerably.
In addition, our teaching continued to flourish. Major course writing efforts included continuing work on replacing our second level courses and the start of work on a new course in quantitative methods for business.
Karen Vines' appointment to a Lectureship has left the Department's Statistical Advisory service unavailable at the present time.
Information on the Department is available through our Web pages at http://stats-www.open.ac.uk
The Department presented four courses (30 CATS points each), MDST242 Statistics in Society
, M246 Elements of Statistics
, M343 Applications of Probability
and M346 Linear Statistical Modelling
. Altogether the Department�s courses attracted a total of almost 2,200 students.
MST121 and M246 were also presented to students of the Singapore Institute of Management. (M346 and M343 will also be presented to Singapore students in alternate years to come.)
Each of the Faculty of Mathematics and Computing�s first level courses, MU120 Open Mathematics
and MST121 Using Mathematics
, contains substantial amounts of statistical material (roughly one quarter of each) with which Gillian Iossif is heavily involved.
Kevin McConway also contributed to the presentation of U205 Health and Disease
and D300 Professional Judgement and Decision Making
The Department continued work on preparing a revitalised statistical offering at second level, with particular attention given to the preparation of M248 Analysing Data
which will replace M246 in 2003. Gillian Iossif is Course Team Chair.
A TV programme associated with M248, called In Search of Certainty
, about the life and works of R.A. Fisher, was made and broadcast on BBC2.
Work also started on the preparation of a new course BM240 Quantitative Methods in Business
. This course is �owned� by the Mathematics & Computing Faculty, within which the Statistics Department is situated, but forms an important contribution to the Open University�s new undergraduate degree in Business Studies. It too is due to start in 2003 and Chris Jones is Course Team Chair.
The new undergraduate Diploma in Statistics
came to fruition in 1999. This qualification is awarded to students who successfully study M246, M343 and M346 (or their predecessors) plus one other course from a list of electives. A total of 47 students obtained this qualification in 1999 and preliminary figures suggest (at least) a further 55 in 2000.
A PhD was awarded to Mona Kanaan for her thesis Cross-Spectral Analysis for Spatial Point-Lattice Processes
(supervisor: P.C. Taylor)
The Department is home to two Research Groups: Multivariate Statistics
(Critchley (chair), Abou-Salama, Garthwaite, Gower, Jones, Larsen, Lunn, Queen, Taylor, Twala, Vines, Constantine (CSIRO, retired), Cook (University of Minnesota), Marriott (National University of Singapore)) and Medical Statistics
(Vines (chair), Farrington, Garthwaite, Kanaan, Lunn, Warwick, M. Lunn (University of Oxford)). A third Research Group, Bayesian Statistics
, will be added at the start of 2001. Research also continues, of course, on topics not covered by these Research Groups. Members of the Department are involved in a variety of research projects, including:
� Influence analysis
