38th Research Students’ Conference in Probability and Statistics Conference Proceedings 3rd – 6th August 2015 Welcome from the Organisers Dear Delegate, We at the University of Leeds take great pleasure in welcoming you to the 38th Research Students’ Conference (RSC) in Probability and Statistics. The RSC is an annual conference that provides an opportunity for research students from probability and statistics to come together in a relaxed environment to discuss their research. Against this backdrop, we hope that new contacts and friendships will be forged. For many students this will be your first experience of presenting your work, and some of you will have the opportunity to chair a session. For those of you attending and not presenting, we hope that you will benefit greatly from observing others and network- ing with researchers working in a similar field. For more information on RSC 2015 see rsc2015.co.uk or join our RSC 2015 - Leeds Facebook group: https://www.facebook.com/groups/rsc15 This year’s conference features plenary speakers Professor Valerie Isham, professor of probability and statistics at University College London, and Professor Sir David Cox, hon- orary fellow of Nuffield College at the University of Oxford. We are no longer looking for potential hosts for RSC 2017, as the University of Durham have volunteered to host. Next year the conference will be held in Dublin. Lastly, we must give special thanks to all of the sponsors, whose support is vital for the continuation of the RSC project and to the previous hosts at Lancaster and Nottingham who have helped us to organise this year’s event.

However, there is a Co-op in the Student Union and various cafes and bars. There are also a number of cafes, a pharmacy and a Tesco Express on Woodhouse Lane, opposite the Parkinson Building steps. Transport: Rail: The First Leeds number 1 bus travels past the main campus entrance every 10 min- utes. The service can be caught from Infirmary Street (Stand B) in City Square or Bishopgate Street (Stop Z1). Both stops are close to the rail station. Alternatively, a taxi fare to the main campus entrance should be about £5 (see page 3). It is a one mile walk (approximately 24 minutes) from the station to the Parkinson building. Air: A taxi from Leeds Bradford International airport to the main campus entrance will cost approximately £20. Arrow taxis have an office at the airport. The Yorkshire Tiger 757 bus service runs from Stand A at the airport to Leeds bus station. From there you can catch regular buses to the University campus. See below in the Bus and Coach section for more information. Bus: For timetables, routes and pricing of coach services to Leeds, please visit the National Express and Megabus websites. Both of these coach operators stop at Leeds bus station. There are regular buses that run from the bus station to the main campus entrance, in particular numbers 6, 28 or 97. For further information please visit the Metro bus information website. There is also a taxi rank located at the bus station. A taxi will take about 10 minutes and cost approximately £5 (see page 3). Car: The main entrance to the campus for cars is on Woodhouse Lane, or Cavendish Lane on some Sat-Nav systems. Parking on campus is limited, and we are also commit- ted to reducing our carbon emissions, so we encourage walking and cycling to the University where possible.Parking for disabled “blue badge” holders is available on campus for visitors. If you are a blue badge holder you are advised to enter the cam- pus via the main barrier on Woodhouse Lane to show your badge. You can then be directed to the nearest available disabled parking bay to the area you are visiting. Blue badge holders do not need to pay to park on campus. 4 4 The RSC 2015 Committee If you have any questions during your time in Leeds please feel free to ask any member of the RSC 2015 Committee.

The history of Leeds can be traced back to the 5th century when the Kingdom of Elmet was covered by the forest of Loidis, the origin of the name Leeds. In the 17th and 18th cen- turies Leeds became a major centre for the production and trading of wool. Then, during the Industrial Revolution, Leeds developed a major industrial centre; wool was the dom- inant industry but flax, engineering, iron foundries, printing and other industries were important. Today Leeds is ranked as a gamma world city by the Globalisation and World Cities Research Network; and is considered the cultural, financial and commercial heart of the West Yorkshire Urban Area. Leeds has plenty to offer from stylish shopping and decadent dining, to contemporary arts and vibrant nightlife. The City Centre boasts breathtaking architecture such as the Leeds Town Hall and the Victoria Quarter as well as a range of attractions such as enter- tainment, sport, theatre and heritage alongside world-class museums and galleries such as the Royal Armouries museum, Leeds Art Gallery and Leeds City Museum.
