Multivariate Models

Objectives

Acquire basic knowledge in multivariate statistics, particularly about the multivariate Normal and Wishart distributions, inference about mean vectors, multivariate regression, canonical analysis and introduction to copulas.
Use the concepts and techniques properly apprehended, along with the R software, in solving most diverse problems of real life.

Evaluation method

 

1. Pre-Requisites

In order to be able to have access to the course evaluation, both to midterms and tests and also to the Exam, students need to have the presence in at least 2/3 on the presential classes.

 

 2. Evaluation 

The recommended form of evaluation consists in:

1st Test - weight: 35%

2nd Test - weight: 35%

Project - weight: 30%

The student who has an average grade (weighted mean) of at least 9,5 (on a 0-20 scale) will be approved in the course.Students who obtained a final grade from tests less than 9.5 (on a 0-20 scale), may have access to a final Exam, in case they have attended at least 2/3 of Labs and 2/3 of Classes.Also the students who had a grade equal or greater than 9.5 from tests may have access to the Final Exam in order to improve their grade.Students with a final grade of more than 18 (on a 0-20 scale) have to go through an oral examination, or their final grade will be equal to 18.
