3rd David Finney Lecture (2019)

Professor Ian Dryden gave the 3rd David Finney Lecture:

Object Data Driven Discovery

Object data analysis is an important tool in the many disciplines where the data have much richer structure than the usual numbers or vectors. An initial question to ask is: what are the most basic data units? i.e. what are the atoms of the data? We describe an introduction to this topic, where the statistical analysis of object data has a wide variety of applications. An important aspect of the analysis is to reduce the dimension to a small number key features while respecting the geometry of the manifold in which objects lie. Three case studies are given which exemplify the types of issues that are encountered: i) investigating differences between authors in corpus linguistics, ii) describing changes in variability in damaged DNA, iii) testing for geometrical differences in carotid arteries, where patients are at high or low risk of aneurysm. In all three applications the structure of the data manifolds is important, in particular the manifolds of networks, covariance matrices, and unlabelled size-and-shapes.

 Ian Dryden is a Professor of Statistics and former Head of the School of Mathematical Sciences at the University of Nottingham, with previous posts at the University of Leeds, University of Chicago and University of South Carolina. Professor Dryden's main research area is statistical shape analysis, a field of Statistics that models geometrical aspects of shape data. His joint monograph, Statistical Shape Analysis, with Applications in R is a leading reference and has been influential in the field, with over 4000 citations. Professor Dryden has also made contributions in object data analysis, manifold-valued data analysis, high-dimensional data analysis, image analysis, and applications of statistics. He is an elected Fellow of the Institute of Mathematical Statistics and his research has been funded by several Research Councils and a Royal Society Wolfson Research Merit Award.
