Mathematical statistics is the science of randomness and probabilities. The research within the subject is divided into probability theory and statistical inference, where statistical inference (how to draw conclusions from random data) is based on probability theory. The activities at the division cover a broad range of areas, from stochastic analysis, random processes, to applied and theoretical multivariate statistical analysis.
Most of the engineering programmes, the mathematical programme and the teacher education programme take at least one required course in mathematical statistics. The courses include probability theory, mathematical modeling of random experiments, and statistical theory and methods. We also give a number of supplementary courses which include advanced probability theory, basic knowledge of stochastic processes, stochastic models for financial markets, experimental design and biostatistics, multivariate statistics, Bayesian networks, and advanced statistical theory.
