Mathematical Statistics and Data Science

The research group in Mathematical Statistics and Data Science studies advanced methods and models for analysing and representing data. We employ probability theory and stochastic processes to rigorously model uncertainty and randomness, and abstract and linear algebra to understand the structure of statistical models and the relationships between their parameters.

Teaching

We teach courses in probability and statistics at all levels. Some of the offered courses are eligible as a basis for an SHV degree in insurance mathematics. Doctoral education in probability and statistics is coordinated by the Finnish Doctoral Education Network in Stochastics and Statistics (FDNSS).
