Time Series and Statistical Learning

Statistics is all about getting data and analysing it and using it to answer questions about the world be that in terms of Economics, Finance or public opinions. The applications are numerous

The LSE has a long and distinguished history in time series analysis and the the Deaprtment of Statistics has a devloping interest in various aspects of statistical learning. At present, the Department's time series and statistical learning group consists of Professors Piotr Fryzlewicz, Leonard Smith and Qiwei Yao, Associate Professors Dr Konstantinos Kalogeropoulos, Dr Clifford Lam and Assistant Professors Dr Matteo Barigozzi, Dr Yining Chen and Dr Xinghao Qiao, as well as associate member Professor Emeritus Howell Tong.

The group also has a strong link with the Econometrics group in the Economics Department, which includes Professors Peter Robinson, Javier Hidalgo and other eminent time series analysts.

Research interests in the group encompass many aspects of these disciplines. We are keenly involved in both theoretical developments and practical applications. Current areas of interest include time series (including high-dimensional and non-stationary time series), data science and machine learning, networks (including dynamical networks), high-dimensional inference and dimension reduction, statistical methods for ranking data, spatio-temporal processes, functional data analysis, shape-constrained estimation, multiscale modelling and estimation, and change-point detection.

The members in the group  provide consultancy service on time series and statistical learning related projects upon request. Recent external Consultancies include EDF (since 2010), Winton Capital Management (2011), Barclays Bank (since 2012), BBC (2012), BrandScience (2012), John Street Capital (since 2012), GfK (2013) and Bonamy Finch (----).

The Centre for the Analysis of Time Series (CATS), which is affiliated with the Department, is at the frontier of multidisciplinary research. The Centre works with EPSRC, NERC, the European Commission and directly with industry funding to continue in tracing the uncertainty in weather and climate forecasts from its origins in observations and models error to statements on the reliability of existing forecast systems and available measures of likely economic impact. The Meteorological Office and the European Centre for Medium Range Forecasts are enabling partners in this research: industrial partners include Munich Re, Lloyds of London, Unilever, NationalGrid UK and EDF Energy. Please visit the Centre for the Analysis of Times Series (CATS) website for further information about the Centre's research.
