Competences and skills that will be acquired and learning results. Further information on this link

The main goal of the course is to provide the students with a set of competences for the understanding and application of statistical concepts and techniques in computer sciences. These competences can be classified as basic, general and specific.
Basic competences:
-Ability to gather and interpret relevant data (usually within their field of study) to inform judgments that include reflection on relevant social, scientific or ethical topics. (CB3)
General competences:
-Ability to apply knowledge of mathematics, statistics, computer science, and engineering as it applies to the fields of computer hardware and software. (PO a)
-Ability to interpret data and results of experiments. (PO b)
-Ability to independently acquire and apply required information related to statistical techniques with the aim of designing, monitoring, and managing computer systems. (PO i)
-Ability to communicate effectively by oral, written, and graphical means, the results of statistical analysis. (PO g)
-Ability to solve mathematical problems arising in engineering. Ability to apply knowledge of linear algebra; differential and integral calculus; numerical methods; numerical algorithms; statistics and optimization. (CGB1)
Specific competences:
-Ability to analyze and sintetize the main information content in a set of univariate and multivariate data.
-Ability to compute probabilities and statistical moments at different dimensions
-Ability to use random variables as a statistical device to model real phenomena.
-Ability to identify the appropriate probability model for specific real situations.
-Knowledge of the properties of point and interval estimation methods, with the aim of doing statistical inference.
-An ability to use statistical models as well as the ability to perform an optimal estimation of the parameters by maximizing the likelihood and minimizing the prediction errors..
-Ability to formulate and testing hypothesis about a population.
-Ability to design lineal models that help to understand and predict real phenomena.
-Ability to use statistical software.

Learning activities and methodology

The learning methodology consists on the following elements:
-Lecture class: Presentation of the main statistical concepts, with their justification and examples. The instructor will illustrate the methodologies with the computer and real or simulated data. Discussion of the concepts with the students. Discussion of the questions and doubts aroused during the self learning process. (PO i y g)
-Exercises class. Classes devoted to solving exercises in small groups. (PO a y b)
-Lab class. In a computer lab, students solve data analysis problems by using a statistical package. They are asked to solve exercises and conceptual problems by using the statistical software. After each class and organized in small groups, they are asked to make a case study that will be evaluated. (PO a, b, i y g)
