 Synopsis:

Students will learn the basics of probabilistic thinking, the ability to synthesize prior and posterior information and learn to work with random variables. They will be able to apply basic models of random variable distributions and solve applied probabilistic problems in informatics and computer science. Using the statistical induction they will be able to perform estimations of unknown distributional parameters from random sample characteristics. They will also be introduced to the methods for testing statistical hypotheses and determining the statistical dependence of two or more random variables.
 Requirements:

Basics of combinatorics and mathematical analysis.
 Syllabus of lectures:

1. Probability  random events, event space structure, probability of a random event and its basic properties.
2. Conditional probability  dependent and independent events, Bayes theorem.
3. Random variables  distribution function of a random variable, continuous and discrete distributions, quantiles, median.
4. Characteristics of random variables  expected value, variance, general moments, kurtosis and skewness.
5. Overview of basic distributions  binomial, geometric, Poisson, uniform, normal, exponential. Their basic properties.
6. Random vectors  joint and marginal statistics, correlation coefficient, dependence and independence of random variables.
7. Random vectors  conditional distributions, sums of random variables.
8. Limit theorems  laws of large numbers, central limit theorem.
9. Statistical estimation  classification and processing of data sets, graphical representation of data, random sample, point estimation, basic sample statistics, sample mean and variance.
10. Interval estimation  confidence intervals for expectation and variance.
11. Hypothesis testing  testing strategy, tests for expectation and variance, their modifications.
