The aim of this course is to provide students a deep understanding of concepts and statistical models, particularly regarding the regression models. It is intended that the student acquire skills that will enable him to build knowledge, develop and interpret statistical models, where there are dependencies that can be modeled by a mathematical expression involving probabilistic notions. The student will show proficiency in applying regression models using generalized linear models, as well as on the respective graphical interpretation and exploitation, aiming at the adjustment to data from a wide range of scientific areas.

Statistical Modelling
Regression Models
Generalized Linear Models
Residual Analysis

At the end of this course students should have acquired skills to allow:
- Feeling able to work with regression models, adjusting them to real problems.
- Reveal proficiency in interpretation, exploration and graphical analysis of results.
- Select and know how to apply the best models to real data in their professional areas.
- Validate models using the graphical analysis of residuals.
- Getting benefit from the capabilities of software suitable for statistical modelling, namely the language R.
