Department assigned to the subject: Statistics Department

Type: Compulsory
ECTS Credits: 3.0 ECTS


COMPETENCES THAT THE STUDENT WILL ACQUIRE 1 Getting and understanding concepts having the chance of being original in the development and/or application of ideas, often in the context of research. 2. Applying the obtained knowledge and ability to solve problems in new environments within wide (or multidisciplinary) contexts related with her/his area of studies. 3. Ability of integrating knowledge and facing the complexity to issue sentences from information that, being incomplete or limited, includes reflections about the social and ethic responsibilities tied to the application of her/his knowledge and sentences. 4. Ability of reporting the conclusions and knowledge, together with the reasons that sustain them, to specialized and non-specialized audiences in a clear, without ambiguity, way. 5. Ability of learning so as to continue studying in a self supervised or autonomous way. 6. Ability to apply the techniques of analysis and representation of information, so as to adapt it to real problems. 7. Ability to identify the most adequate statistical model for each real problem and knowing how to apply that model for the analysis, design and solution of the problem. 8. Ability to find, either individually or in a team, scientifically feasible solutions for complex statistical problems from the real life. 9. Ability to summarize the obtained conclusions from those analysis and present them in a clear and convincing way in a bilingual environment (Spanish and English) both in written and orally. 10. Being able to generate new ideas (creativity) and anticipate new situations, in the context of data analysis and decision making. 11. Apply social abilities for team work and for relating with others in an autonomous way. 12. Apply the advanced techniques of analysis and representation of information, so as to adapt it to real problems. 13. Apply advanced Statistical Inference knowledge to the development of analytical methods for real problems. 14. Using free software such as R and Python for the implementation of the Statistical Analyses. 15. Predicting and representing eventual associations between random phenomena, related with real problems and reflected in the collected data, by applying multivariate analysis concepts. 16. Developing and applying complex statistical models for non necessarily independent samples of random variables by applying Bayesian analysis concepts. 17. Applying the advanced Statistical foundations for the development and analysis of real problems related with the prediction of a response variable. 18. Applying non-parametric models for the interpretation and prediction of random phenomena. 19. Applying optimization techniques for the estimation of the parameters of complex sampling models. 20. Correctly identifying the corresponding type of Statistical analysis needed for specific objectives and data. 21. Applying Statistical modeling in the treatment of relevant problems appearing in the scientific world. 22. Applying models for supervised and non-supervised learning. 23. Modelling complex data with stochastic dependence.
