Statistically Speaking... News and views from the Statistics Department Official Newsletter of the Department of Statistics, University of Warwick Issue 4: June 2014 New starters & congratulations Welcome to the fourth issue of “Statistically Speaking...” - a termly publication designed for current and past students and staff of the Statistics Department at the University A warm welcome to the Department’s most recent starters! Congratulations to Catalina Vallejos Meneses of Warwick. Thank you to all who contributed to this issue or participated in its production in any way. Larbi Alili, Eleanor Ingram Managing Editors Dr Yacine Barhoumi Started on 1st May 2014 Mr David Kinmond Started on 8 May 2014 Han Feng Lorna Barclay for successful completion of their PhDs First impressions For the past 9 months, I have been happily working as a new member of the statistics department. I often get asked by my peers in the USA how I am finding my new position, because it is a big change in location and departments (I was previously in the Department of Psychiatry at UC San Diego). I continue to give the same response: I absolutely love it here. Dr Mark Fiecas Professor Chenlei Leng Believe it or not, I have been in Warwick for almost one year. It has been an exciting transition so far. Compared to my previous institute in Singapore, there is a whole lot more going on research wise: seminars, workshops, discussion groups and so on. I wish I could have attended as many talks as possible, and realized that is impossible. Currently, I am looking forward to building up my research team in the near future. My 9-month impression of the department is very positive. I am very happy to be surrounded by many bright statisticians, especially by so many talented students. There is a cooperative and collaborative atmosphere here, which led to the many fascinating discussions I have had with other members of the department on exciting potential projects. Consequently, I have had to step outside of my comfort zone in my primary area of application (brain imaging), but doing so has certainly given me new ideas and fresh approaches to my research in statistical methodology. Finally, I am There are also other changes since my move, for example, glad that the students and staff have been approving, sometimes I get up much earlier (but sleep as much as I used to even enabling, my love for desserts.

By Martine Barons http://www2.warwick.ac.uk/fac/sci/statistics Participation in the AIMS Programme I was able to travel to Africa during my study leave, to South Africa, Ghana and Uganda, giving seminars and teaching while continuing with research projects. In Johannesburg, I gave seminars on life expectancy of people with cerebral palsy to two different audiences: lawyers who specialise in medico-legal work, and paediatrician, from students to consultants, at the Wits University Hospital. Lawyers who represented braindamaged infants as well as those who represented doctors and hospitals were keen to discuss the implications of my collaborative research with several UK cerebral palsy registers. At the hospital, I was able to see some very tiny babies who were cared for by those in my audience. I then spent December by the sea and mountains at Muizenberg, near Cape Town, teaching a course on analysis of life-time data at the African Institute for Mathematical Sciences. AIMS is a centre for tertiary mathematical education and research, founded in order to build capacity for African initiatives in education, research, and technology. The main AIMS programme is a year's course, which intended to prepare African graduates with mathematically-based degrees for postgraduate study in, for example, South Africa, Belgium, UK or North America. There are introductory courses, and then a series of 6 three-week blocks in which students choose two out of three courses. All courses are taught by visiting lecturers, volunteers from Europe and North America as well as Africa. Students at AIMS are selected from many African countries, and have often struggled to get an education in countries where only primary education is mandatory. They are often older than UK graduates, leave families behind, and try to save their allowances to send home. Motivation and commitment is high, and as the centre is fully residential, students can work in the library or computer laboratory at any time: I often noticed many people in the lab as I went upstairs to my bedroom. As women are often expected not to go out after dark, this freedom to study is valued. Students appreciate being able to find lecturers in their offices after dinner. Instruction is in English, and intensive language teaching is provided for those whose first languages are French, Malagasy or Arabic. Students gain considerable experience in programming, and the use of LaTeX and mathematical software programs. The course is very demanding: in the review section, students choose two out of three options. Each day they have two hours instruction for each review course, and an additional hour of English or computing. Within three weeks, they have to master a new topic, and complete a series of assignments. It is lovely to be told by students from pure mathematics, physics and engineering backgrounds that they have come to realise how exciting and useful statistics is, and value learning the powerful, free, statistical software R. I gave a short talk on the many careers in statistics, as well as a research seminar. When I visited statistical colleagues at the University of Cape Town, I heard a taught M.Sc. Statistics was offered in 2013. I hope many AIMS and other students will benefit. Students also work long days, and much of the weekend. I led a relaxed walk up the mountain, having heard that in the previous block, a group had hiked over the mountains walked for 10 hours to reach Table Mountain. Going up was hot for me, in shorts and it's difficult to imagine hiking fully covered as the Muslim women do. My route included a stop at an excellent ice-cream shop. I was asked what I thought of Scottish independence: it's not all mathematics! In January, I taught probability and statistics at AIMS Ghana, which opened in 2012. AIMS Ghana is also by the sea, but much else is different, including being in a small village rather than a cosmopolitan city. An experienced and enthusiastic cook provided African meals, with banku, fufu and about eight different kinds of porridge for breakfast. Some students kept to African ways, and ate with their fingers, others regarded the year as a chance to practice with knife and fork. Most of us ate on the balcony outside, which was pleasant once the breeze started, usually by about 11am. Overnight temperatures were 24C, and walking along the beach to a bar under coconut trees was a hot experience. There is little concern about crime: the main building has four entrances which are not locked, and two relaxed security guards. Laptops are left on desks in offices - well, on desks. A balcony is not usually called an office! Electricity supplies are variable, so the computer laboratory has laptops rather than desktops. The general level of structural work is laid back. The students were again enthusiastic and diligent, as photos of groups working 8.30 on Friday evening show. A Zambian student told me that many of the staff who taught him were graduates of AIMS South Africa, a nice example of successful capacity building. Uganda was my third destination, cooler than Ghana but equally friendly. I gave a seminar on epilepsy drugs at Makerere University College of Health Sciences. The audience was attentive, and I was impressed by the range. By Jane Hutton http://www2.warwick.ac.uk/fac/sci/statistics News and Events The Tony Lawrance Seminar On March 25th 2014 the Department of Statistics hosted an afternoon of seminars to mark the recent retirement of Emeritus Professor Tony Lawrance. In their seminars Professors Howell Tong and Anthony Atkinson of the London School of Economics discussed recent advances in two of Tony Lawrance’s long-standing research interests, time series analysis and regression diagnostics. Then after tea Tim Davis, one of Tony’s former research students and now Honorary Professor at Warwick, described some of his pioneering statistical work in the automotive industry, including some of the engineering problems that had been tackled in joint work with Tony. The final seminar was by Tony himself, reflecting on highlights of his statistical career and on his current and continuing research interests. The proceedings started with a lunch in Radcliffe House and ended with a cheese and wine reception in the Statistics Common Room, followed by an informal dinner for the speakers and Tony’s invited guests. It was a great pleasure to welcome so many of Tony Lawrance’s statistical friends and former colleagues to this celebration of a long and distinguished academic career.

There were an estimated 70,000 visitors to the Big Bang Fair and over the 4 days we engaged with about 7,000 individuals, predominantly 7-19-year-olds, their parents and teachers, most of whom would not have come to an open day. The Warwick stand was continually busy and well-placed on the corner of a thoroughfare to attract passers-by. We were able to spread beyond the 4 tables and some volunteers went out into the crowds and brought people to our stand. The mathematical sciences part of the Warwick stand offered a choice of 10 puzzles, including ‘pick 15’ which invited two participants to go head-to-head to select 3 numbers (one at a time, in turn, without replacement) to sum to 15 from integers 1 to 9. After several rounds, we asked which number was the best strategy to pick first. The ‘reveal’ on this activity was to show that the problem can be expressed in a different format, as a magic square with 5 at the centre. It is then obvious that the optimal strategy is to pick 5 first. This activity demonstrated, in a way accessible to the 11-15 target age range, that reframing a problem in terms of a problem with a known solution can make it more tractable. In addition, we ran a competition to make all the integers using all of 2,0,1,4 and any mathematical operators. Each day a prize was awarded – a copy of Simon Singh’s book ‘The Simpsons and Their Mathematical Secrets’ and a certificate were sent to the child via their school. Martine said, “We counted how many visitors we had by giving everyone a sticker. I was alone on the stand on Friday morning and saw about 100 young people. It was delightful to see the realisation dawn on their faces as we demonstrated that maths is more than doing sums! It was tiring to maintain smiling enthusiasm in a noisy environment without a break, but it was also great fun. I recommend being involved next year.” The 5 x 3 metre space cost £18,000 and total cost estimated at £25,000. Funding for this was approved by Professor Pam Thomas, Chair of the Board of the Faculty of Science. Big Bang Fair 2015 will also be held at the NEC, and the plan is to have a Warwick presence again, subject to funding being available. The other people on the mathematical sciences table were: David Mond (lead), Dmitriy Rumynin, Florian Theil, Nicholas Jackson & Edwin Lim (WMI) and Alistair Tucker & Ben Collyer from Complexity. Liz-Buckingham-Jeffrey also from Complexity worked at BBF as a STEM ambassador.

I visited the Milverton Primary School, Leamington Spa, where I helped each of the 31 students make brains out of coloured plasticine, explaining how the different major lobes of the brain are responsible for different aspects of behaviour and thought, like vision, hearing and memory. After practicing a word "game" (i.e. a verbal fluency experiment), I showed the children MRI images of my own brain, as well as functional MRI results of my brain doing the very same word game. I concluded the presentation with an explanation of how statisticians, a special type of mathematician, are needed to make sense of the data that comes out of the MRI machine. At the end a child raised their hand and asked, "Why do you do this?", and I answered "This a way to have fun with math and pictures."
