2009 was, inevitably, another active year for Statistics at the Open University in both research and teaching.

The revision of M346 Linear Statistical Modelling was successfully presented for the first time in 2009. Substantial work continued on both our new web-based course M347 Mathematical Statistics and on the revision of M343 Applications of Probability. Our contribution to the Science Faculty's short course programme, SMK184 Chance, Risk and Health, came to an end. The Group's courses attracted a total of over 2200 students in 2009.

The end of 2009 saw some changes in personnel/positions. Our long employment of John Gower came to an end as he retired (and not for the first time!). We are delighted to say that John is continuing to work with us in the capacity of Visiting Professor with the title of Emeritus Professor shortly to be conferred. Casper Albers left his postdoctoral position (in the summer) to take up a post as University Lecturer in Statistics at the University of Groningen in the Netherlands. The postdoctoral positions of Mounia Hocine and Karim Anaya also came to an end. Mounia is now Ma�tre de Conferences at CNAM, the Conservatoire National des Arts et M�tiers, in Paris, while Karim remains with us in a different postdoctoral capacity. Steffen Unkel has also graduated from research student to research associate. These changes have been met with sadness, but our very best wishes, where people have gone away, and by relief and pleasure at their continued presence here when they haven't!

We are delighted to be able to report the promotion during 2009 of Kevin McConway to a Chair in Applied Statistics.

In the course of the year, members of the Department published 21 papers in refereed journals (see Section 6), including some of the very best outlets. Pre-publication papers and other research material can be found in our technical report section.
2009 was a particularly successful year for our international profile with members of the Group taking part in numerous international conferences and hosting a large number of research visitors. And our domestic profile was enhanced too by no fewer than three contributions to our long-standing series of Open University conferences in Statistics.

The Statistical Advisory Service to support research in other departments at the Open University continued to run. Its usual leader, Alvaro Faria, was on study leave in Portugal for much of the year but Paul Garthwaite, assisted at various times by Paddy Farrington, Karen Vines and Heather Whitaker, continued to provide advice. A website explains the service:

Further information on the Department is available through our web pages at



The Department presented four courses of 30 CATS points each, namely, M248 Analysing Data, M249 Practical Modern Statistics, M343 Applications of Probability and M346 Linear Statistical Modelling, and one course of 10 CATS points, SMK184 Chance, Risk and Health, which ran four times in the year.

Each of the first level mathematics courses, MU120 Discovering Mathematics and MST121 Using Mathematics, contains substantial amounts of statistical material (roughly one quarter of each) with which Alvaro Faria, Heather Whitaker and Nickolay Trendafilov were involved.

Kevin McConway contributed to the presentation of SDK125 Introducing Health Sciences.

The Group has continued production of M347 Mathematical Statistics. As well as enhancing our third level provision with a new course that gives the theory behind the methods, this course is notable for leading the way within the Department of Mathematics and Statistics in terms of electronic presentation. M347 is to be presented entirely on-line, and we are investigating ways of making the very best use of modern web-based tools. Catriona Queen and Chris Jones are course team co-chairs; Paddy Farrington, Ian Martin and Heather Whitaker are also course authors; and Robert Hasson (Applied Maths) has an important role, especially in facilitating the interface between Latex drafting and the University's Virtual Learning Environment.

Gillian Iossif is leading the revision of M343 Applications of Probability. This old, but very successful, course is in need of a certain amount of improvement and updating. Gillian is single-handedly authoring the entire revision. She has help in the form of Nickolay Trendafilov with respect to software aspects.


Our courses are compulsory components of degrees in Mathematics and Statistics, Computing and Statistics, Mathematics and its Learning. Economics and Mathematical Sciences and Business Studies with Accounting, as well being specified options in certain other awards. Forty-four students were awarded the Mathematics and Statistics degree in 2009. The undergraduate Diploma in Statistics is now awarded to students who successfully study M248, M249, M343 and M346 (or their predecessors). A little under 100 students are awarded the Diploma each year.

Ph.D.s awarded

Swarup De for his thesis A Bayesian Space-Time Dynamic Linear Model for Radioactivity Deposition after a Nuclear Accident (supervisors: A.E. Faria and K.J. McConway).
Steffen Unkel for his thesis Factor Analysis of Data Matrices: New Theoretical and Computational Aspects with Applications (supervisors: N.T. Trendafilov and M.C. Jones)

Research interests

The Department is home to three Research Groups:

Multivariate Statistics: Critchley (chair), Albers, Anaya, De, Faria, Garthwaite, Gower, Gragn, Jones, Queen, Trendafilov, Unkel, Vines, Constantine (CSIRO, retired), Cook (University of Minnesota), Marriott (University of Waterloo), Taylor (University of Hertfordshire).

Bayesian Statistics: Queen (chair), Albers, De, Faria, Farrington, Garthwaite, McConway, Vines, Whitaker.

Medical Statistics: Whitaker (chair), Farrington, Garthwaite, Hocine, Unkel, Vines.

Clearly, these three general groupings cover a huge variety of research projects in Statistics. Inter alia, they organise informal internal research meetings. 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, traffic modelling and ecology.

For details, see the publications, talks and other items to follow.

And, again, a roundtable discussion, including contributions from Phil Dawid (University of Cambridge), Pia Larsen (University of Southern Denmark), Eva Riccomagno (University of Warwick) and Paul Vos (East Carolina University).

We ran our sixth Annual Research Students� Research Day, where speakers were Tom Collins, Fadlalla Elfadaly, Doyo Gragn, Angela Noufaily, Alun Owen, Steffen Unkel and John Urquhart.

And we still found time for an internal research morning at which speakers were Doyo Gragn, Paul Garthwaite, Paddy Farrington, Karen Vines and Chris Jones.
