SCIENTIFIC PROGRAMS AND ACTIVITIES

September 26, 2017
THE FIELDS INSTITUTE FOR RESEARCH IN MATHEMATICAL SCIENCES

April 21-24, 2015
Workshop on Complex Spatio-temporal Data Structures:
Methods and applications

Fields Institute, 222 College St., Toronto

Organizer:
Patrick Brown and Jamie Stafford, University of Toronto

This four day workshop will bring together statistical methodologists and applied statisticians with a variety of expertise and research areas but with a common interest in complex and non-standard spatio-temporal problems. 'Complex' data includes that which is observed irregularly or in an unbalanced fashion, aggregated spatially to arbitrary and variable regions, and/or exhibiting hierarchical but non-nested correlations. Distributions and likelihoods for such data often depend on the behaviour of the underlying process throughout it's entire spatial extent and not only at the locations where data are observed. The high dimensionality of the resulting problem requires inference methodologies exhibiting a combination of model simplifications, approximations of estimators and likelihood functions, and/or computational and algorithmic efficiencies. Unlike many other 'big data' problems, however, an understanding of the physical properties of the spatio-temporal process in question often enables many simplifying assumptions to be made which lead to convenient and enabling mathematical properties (i.e.Markov property, stationarity, various forms of conditional independence).

Examples of statistical applications covered will include:

  • Spatial epidemiology: inference on variations in disease risk in space and time using complex forms of case incidence data
  • Forestry: inference on forest fire ignitions with location data subject to aggregation and censoring
  • Fisheries: inference on species abundance from ocean surveys and catch data

Related areas of statistical methodology include:

  • Bayesian inference for parametric models
  • Non-parametrics and smoothing
  • Functional data analysis
  • Statistical computing

Format

The workshop will be structured to maximize the amount of interaction amongst the attendees, and aims to encourage problem solving, identification of open problems, and matching of emerging methods development to relevant areas of applied statistics research. Each day will involve two or three 45-minute talks, each followed up by a pre-arranged discussant and ample time for general questions and comments. Talks will include overviews on statistical issues in substantive applied areas (public health, forestry, fisheries), and recent methods developments. The remainder of the conference will involve a number of shorter presentations, panel discussions, and breakout groups.
