Objectives
Students should be able to distinguish and recognise the properties of the different stochastic processes studied, such as: the Poisson process, renewal processes, Markov chains and Brownian motion. Students should also be able to use the most common processes as modelling tools. Students should also manage to simulate the different processes and use their respective properties to answer concrete problems.
Learning outcomes and competences
The program includes several tools for the analysis of stochastic processes and its applications in several areas. Special attention is given to the understanding of concepts and methods conducing to its application in interdisciplinary areas. Each method is introduced with examples that are solved in class so that the student has a good understanding of the examples and of their solution. A parallel supplementary exercise list is also proposed. In addition, the student must develop computational projects where the methodologies introduced are applied to the real world.

Teaching methods and learning activities
Theoretical lectures will be essentially expository with the main purpose of teaching the theoretical background that supports the properties and main results. TP lectures will be used to present and illustrate the main topics by studying examples and solving exercises.
