Program Description

Statistics is concerned with the development and use of mathematical and computational methods for the collection, analysis, and interpretation of data in support of scientific inquiry, informed decision-making, and risk management. It calls on a broad range of tools from probability theory to computer-intensive techniques. The main areas of research by statisticians in the ISM network include

  • Bayesian inference and Markov chain Monte Carlo methods
  • causal inference
  • computational statistics
  • dependence modeling and multivariate analysis
  • directional statistics
  • empirical process theory
  • extreme-value analysis
  • high-dimensional data modeling
  • machine learning
  • nonparametric statistics
  • statistical learning
  • survey sampling
  • survival analysis
  • time series

Statistical research is largely motivated by collaboration with other disciplines. It finds applications in many fields, including biology, environmental science, finance and insurance, health sciences, hydrology, market research, and social sciences. With the abundance of very large and complex data sets coming, for example, from the social media and digital processes, financial transactions, astronomy, genomics, meteorology or Big Science like the Giant Hadron Collide, the statistical treatment and analysis of Big Data has become a major challenge of modern statistics.

Program Members

Academic Program

The statistics program gives an opportunity to graduate students to study in these two major areas of modern statistics. The curriculum allows the students to get well acquainted with the basic elements of mathematical statistics, decision theory and applied statistics. Furthermore, advanced graduate courses can be offered in some more specialized areas.

This program welcomes graduate students with a good background in calculus, mathematical statistics, numerical analysis, and probability (all at the undergraduate level). To get strong training in decision theory and mathematical statistics students should take the basic course in measure and integration (for PhD students) and at least three courses at the intermediate and advanced levels.
