Statistics for Informatics
- Department of Applied Mathematics
The students will learn the basics of the probability theory, elements of information theory and stochastic processes, and some methods of computational statistics. They will understand the methods for statistical processing of large volumes of data. They will get skills in using computational methods and statistical software for these tasks.
Knowledge in differential and integral calculus, elementary knowledge in probability and statistics.
