Course detail

Analysis of Experiment and Forecasting

FSI-SEP-AAcad. year: 2024/2025

The course provides an introduction to the theory of stochastic processes. The following topics are dealt with: types and basic characteristics, queueing theory, Markov chains, stationarity, autocovariance function, decomposition of stochastic processes, ARMA processes. Students will learn the applicability of the methods for the description and prediction of the stochastic processes using suitable software on PC.

Rules for evaluation and completion of the course

Course-unit credit requirements: active participation in seminars, demonstration of basic skills in practical data analysis on PC in a project, and succesfull solution of possible written tests.

Examination: oral exam, questions are selected from a list of 3 set areas (30+30+40 points). At least a basic knowledge of the terms and their properties is required in each of the areas. Evaluation by points: excellent (90 - 100 points), very good (80 - 89 points), good (70 - 79 points), satisfactory (60 - 69 points), sufficient (50 - 59 points), failed (0 - 49 points).


Attendance at seminars is compulsory whereas the teacher decides on the compensation for absences.

Aims

The course objective is to make students familiar with the principles of the theory of stochastic processes and models used for their analysis as well as with estimation algorithms of their parameters. At seminars, students apply theoretical procedures on simulated or real data using suitable software. The semester is concluded with a project of analysis and prediction of a real stochastic process.


The course provides students with basic knowledge of modeling stochastic processes (Queueing theory, Poisson processes, Markov chains, decomposition, ARMA) and ways to estimate their assorted characteristics in order to describe the mechanism of the process behavior on the basis of its observations. Students learn basic methods used for real data evaluation.
