Learning activities and methodology

Theory (3 ECTS). Theory classes with supporting material available in the course's web page. Practical classes (3 ECTS). Problem-solving classes. Practical classes in computer rooms. Weekly individual tutoring sessions.
The teaching methodology will be eminently practical, being based on the study of diverse data sets through multivariante analysis techniques, both in the theory and practical classes, as motivation and illustration of the theory.
