Teaching language

Objectives

 It is expected that, jointly with new statistical methodologies, the students can see real applications of the concepts previously learnt in "Probability and Statistics". Theory-wise, the simplest methods of statistical inference including some theory on estimators and point estimation and hypothesis testing. 

It is also expected that the students acquire familiarity with the programing language and software environment R, in the framework of problems solving.

Learning outcomes and competences

Upon completing this course, the student should:

- have a good insight of the fundamental concepts and principles of statistics, and in particular those from basic inference statistics.

- know the common inference statistical  methods and how to apply them to concrete situations;

- be able to identify and formulate a problem, to choose adequate statistical methods and to analyze and interpret in a critical way the obtained results;

- be able to apply the studied models, and more generally to perform simple data analyses, in R

Working method

Program

1. Statistics. Unbiased and consistent estimators. Most usual statistics, with emphasis on the sample mean and sample variance.


2. Point estimation. The method of moments. Maximum likelihood estimation. Properties of the maximum likelihood estimators.


3. Joint distributions. Bivariate gaussian and multinomial.


4. Hypothesis testing. Errors of type I and type II, test statistic, power of a test. One- and two-sample parametric tests. Relation between hypothesis tests and confidence intervals. Non-parametric tests: goodness-of-fit, location, independence and homogeneity.


5. Correlation analysis. Pearson and Spearman correlation coeficient. Hypothesis testing.

Teaching methods and learning activities

Lectures and classes: The contents of the syllabus are presented in the lectures, illustrated with several examples. In the practical classes, exercises and related problems are solved and discussed. Several real data sets will be analyzed using the statistical software R. All resources are available for students at the unit’s web page.

Eligibility for exams

Attendance to the course unit, as defined in the 
following terms, is compulsory: If a student 
is regularly enrolled, he/she cannot exceed the limit 
number of absences corresponding to 25% of the 
practical classes.

Students covered by the situations provided for by law 
are exempt from verifying the attendance conditions 
mentioned above (Art. 10, Regulamento Geral para  
Avaliação dos discentes de primeiros ciclos, 
de ciclos de estudos integrados de mestrado e 
de segundos ciclos da Universidade do Porto). 

Mandatory attendance is suspended as long as the UP 
contingency plan against the COVID-19 pandemic persists.

Calculation formula of final grade

The evaluation method was changed due to the appearance 
of the COVID-19 pandemic.



The evaluation will be made exclusively by final exam 
("época normal" and "época de recurso")

Students with a grade higher than 18 will be subjected 
to an assessment test, and the final result will never 
be less than 18.

Classification improvement

Improvement of the classification at the time of appeal ("época de recurso") can be made.
