2006 was, inevitably, another active year for the Department in both research and teaching. Regrettably, this is the last time that this form of words can be used because at some time in 2007 the Department of Statistics will cease to be: we will be incorporated with the current Department of Mathematics into a single new, large, department. There is little logical reason for this change and few obvious positives to be gained; we can only hope that negatives will be few and minor. This is an enormous pity for a thriving, excellent and happy Department (and for the discipline of Statistics).
One aspect of our success is stability in academic personnel. Relatively small changes are that Heather Whitaker's new appointment (from October) is as half-and-half lecturer and research fellow, while Patrick Musonda became a research fellow on completion of his research studentship. Unfortunately, we lost our popular and efficient secretary Val Spearman to retirement and a new life in Spain! Kevin McConway relinquished his Headship of the Department in mid-term to be crowned Associate Dean (Curriculum) in the Faculty of Mathematics and Computing.
Particular success was achieved this year in obtaining substantial research grants from the Research Councils (see Section 11).
In the course of the year, members of the Department published a book and another 26 papers in refereed journals (including one Royal Statistical Society read paper) (see Section 6). Pre-publication papers and other research material can be found in our technical report section
Our teaching continued to flourish. We ran five 30 point courses, three at second level and two at third, a new 10 point course at Level 1, and continued to contribute to other courses in Faculty and University. The Department's courses attracted a total of about 2,400 students. We also completed a major new course production effort (details below).
Alvaro Faria and Paul Garthwaite continued to run a Statistical Advisory Service to support research in other departments at the Open University.
Further information on the Department is available through our web pages at http://statistics.open.ac.uk/
The Department presented five courses of 30 CATS points each, namely, BM240 Quantitative Methods in Business, MDST242 Statistics in Society, M248
Analysing Data, M343
Applications of Probability and M346
Linear Statistical Modelling, and, for the first time, one course of 10 CATS points, SMK184 Chance, Risk and Health, which runs four times a year.
This year was the last in which MDST242 was presented. This venerable course partially rewritten during the course of its life has been presented every year from 1983 (a total of 24 times) and has been studied by almost 14,000 students.
Each of the Faculty of Mathematics and Computing's first level mathematics courses, MU120 Open Mathematics and MST121
Using Mathematics, contains substantial amounts of statistical material (roughly one quarter of each) with which Paul Garthwaite and Alvaro Faria were involved.
Kevin McConway contributed to the presentation of U205 Health and Disease.
The final year's hard work on the production of our new second-level course in Statistics, M249
, entitled Practical Modern Statistics, took place under the chairing of Paddy Farrington and the academic editing of Gillian Iossif. The course is being presented for the first time in 2007. It consists of four blocks on the topics of Bayesian statistics, medical statistics, multivariate statistics and time series analysis, respectively. M249 rounds off our undergraduate Diploma in Statistics (by replacing the elective element; see below) and will also form a core component of other degrees involving Statistics.
Kevin McConway contributed to the production of SDK125
Introducing Health Science.
Our courses are core components of degrees in Mathematics and Statistics
and in Computing and Statistics
which were introduced during 2004 and will have their first graduates in 2007. They are also core components of the existing degrees in Mathematical Sciences and in Economics and Mathematical Sciences, while BM240 is part of the BA in Business Studies.
The undergraduate Diploma in Statistics is currently awarded to students who successfully study M248 or BM240, M343 and M346 (or their predecessors) plus one other course from a list of electives. Around 100 students are awarded the Diploma each year.
Christopher Banks for his thesis Sea Ice Thickness and Iceberg Distribution in the Southern Ocean (joint with Earth Sciences; supervisors: M.A. Brandon, Earth Sciences, and P.H. Garthwaite).
Patrick Musonda for his thesis The Self-Controlled Case Series Method: Performance and Design in Studies of Vaccine Safety (supervisors: C.P. Farrington and F. Critchley).
Avik Sarkar for his thesis Term Burstiness: Evidence, Model and Applications (joint with Computing; supervisors: A. DeRoeck, Computing, and P.H. Garthwaite).
Linjuan Sun for her thesis Simple Principal Components (supervisors: S.K. Vines and F. Critchley).
The Department is home to three Research Groups:
(Critchley (chair), Albers, Faria, Garthwaite, Gower, Jones, Queen, Taylor, Trendafilov, Unkel, Vines, Constantine (CSIRO, retired), Cook (University of Minnesota), Marriott (University of Waterloo)).
(Queen (chair), Albers, Faria, Farrington, Garthwaite, McConway, Vines, Whitaker).
Medical Statistics (Whitaker (chair), Farrington, Garthwaite, Jenkinson, Musonda, Vines).
Clearly, these three general groupings cover a huge variety of research projects in Statistics. Research also continues, of course, on topics not directly covered by these Research Groups, of which distribution theory, kernel smoothing, robust statistics, time series forecasting and influence analysis are but a small selection. Strong ongoing collaborations continue in areas such as medicine, psychology and ecology.
