Cycles of Study/Courses
Teaching language
Suitable for English-speaking students
Objectives
1. Enable students with advanced regression methodologies, including repeated measures and longitudinal data analysis: general linear model and generalized linear models with mixed effects.
2. Implement statistical analysis in suitable software
3. Promote critical thinking throughout the statistical modeling process (data collection, modeling, interpretation of results, ...)
Learning outcomes and competences
1.Identification of scenarios of repeated measurements, longitudinal data or survival analysis
2. Identification of the most adequate model to the context of a given problem, among the studies models
3. Application and implementation of the studied models in R
4. Adequate interpretation of the results
5. Promotion of a critical thinking along the whole modelling process
Working method
Presencial
Pre-requirements (prior knowledge) and co-requirements (common knowledge)
Previous knowledge on multiple linear regression and logistic regression (obtained, for instance, in Applied Statistics from the 1st semester)
Program
Multiple testing. Control of the Family-Wise Error Rate (FWER) and False Discovery Rate (FDR).
General linear model. Modelling of the variance-covariance matrix of the random errors.
Mixed-effects linear model.
Experimental Design: randomized complete-block designs; factorial designs; ANOVA models with random effects.
For each of the listed models, the following will be studied: models and their theoretical assumptions, parameters’ estimation and inference processes, modeling and implementation in the statistical programming language R, model selection and comparison, diagnostics, interpretation of results. Several examples of application will be presented.

Teaching methods and learning activities
Classes are of theoretical-practical type. They include theoretical exposition, implementation of the studied models in the statistical programming language R, and interpretation and discussion of the results obtained. The examples presented and proposed exercises will start from real data, whenever possible.
Teaching methodologies will be adjusted to allow students to integrate the objectives of the course.

Eligibility for exams
Sem requisitos.
Calculation formula of final grade
Students have to perform a written report, with an oral presentation, and a final exam.
The assignement is mandatory and its mark cannot be improved.
The final mark will be given by
0.6*A + 0.4*E
where
A: mark of assignment
E: mark of the exam.
For final approval, students have to score more than 5 values (out of 20) on each of the evaluation components.
Classification improvement
The mark obtained in the assignements cannot be improved.
Observations
The way the course will be provided is conditioned to the limitations imposed by FCUP according to the evolution of the pandemic COVID19.
