Abstract
This course aims to provide a solid introduction to probability theory and mathematical statistics. The fundamental concepts and mathematical tools for modeling and analysis of random phenomena will be presented and discussed.
Learning Objectives
- To provide students with the knowledge of the theoretical aspects and modeling tools related to probability theory.
- To provide students with the knowledge of elementary techniques to analyze probabilistic models.
- To present and study some fundamental distributions of random variables.
- To develop students' ability to apply the knowledge acquired during the course and to use probabilistic models in concrete situations, recognizing the appropriate frameworks and analytical tools related to the study.
- To outline the basic concepts and methods of mathematical and applied statistics.
- To give practical skills in applying statistical methods in applied research.
- To give an idea of the applied methods of multidimensional statistical analysis.
Expected Learning Outcomes
- The concepts of random variables will be generalized to random vectors. It will be introduced the concepts of multivariate distributions.
- The students are expected to learn the concept of random variable, some distribution functions, expected value and variance. Also, they will have the opportunity to relate random problems with random variables.
- The students are expected to learn the operations between sets, the notion of σ-algebra, Kolmogorov's axioms and properties of probability measures.
- The students will have the opportunity to model random experiments where the knowledge of continuous random variables is required. The concepts of expected value and variance for continuous random variables will be generalized. Also, the students will learn some of the main inequalities in Probability Theory.
- The students will learn about some convergences that are used in Probability Theory. LLN and CLT and their applications will be discussed.

Interim Assessment
- 2023/2024 2nd moduleThe final grade will be an average of the two modules/part of the course, with 50% for the part "Probability Theory" and 50% for the part "Mathematical Statistics". For module 1: 45% * N1 + 55% * N2 where N2=End of module Exam, N1= weighted averaged of homework assignments, seminar participation and mid-module test
