Linear algebra. Mathematical analysis. Probability.
In this course, the concept of Inference, in its inductive version, must be fundamentally learned.
The concepts of Modeling, Estimation (by point and intervals) and Goodness of fit must be introduced. And the linear regression techniques.
The students will have to learn:
1. The descriptive and exploratory statistics that will allow to extract and summarize efficiently information of the data.
2. Statistical Inference: how the Statistics quantifies the uncertainty of the information extracted from the data.
3. The modeling of populations, the estimation of parameters, especially maximum likelihood, and the planning and resolution of contrasts of hypotheses (parametric and non-parametric).
3. Basic properties of optimal estimators: invariance, sufficiency, efficiency, bias, variance and asymptotic properties.
4. Establish and solve applied problems. With the examples, the resolution of problems and the practices with statistical software (R), the student will work with concrete models and with real data: inferential for the most important parameters of one and two normal populations. Adjustment tests, inferential methods for the linear model.
The subject is structured in four chapters:
Topic 1: Introduction to Inference.
Summary of the fundamental tools of probability: LLN and CLT.
Binomial and normal. Comparison of two proportions. Pearson test.
Simulation and goodness of fit.
Topic 2: Modeling and estimation.
Normal, gamma, Pareto, Poisson, negative binomial distributions, ...
Estimation methods: moments, maximum likelihood, minimum least squares.
Generating functions.
Topic 3: Assessment of estimators and asymptotic theory.
Bias, mean quadratic error, consistency, asymptotic normality, ...
Cramér-Rao inequality. Fisher information. Efficiency
Asymptotic distribution of the maximum likelihood estimator .
Likelihood ratio test. Scoring and Wald test.
Fisher Theorem. Student Laws, Pearson's χ2 and Fisher's F.
Contrasts. Null and alternative hypothesis. Type of error
Comparison of two populations and analysis of the variance.
Bootstrap
Topic 4: Linear regression.
Linear regression. Estimate and contrasts.
Unless the requirements enforced by the health authorities demand a prioritization or reduction of these contents.
We have theoretical classes, problems and practices.
The new subject will be introduced primarily in theory classes, but it will be necessary to extend the teacher's explanations with the student's autonomous study, with the support of the reference bibliography. Student participation will be valued at the exhibitions of the student. teacher There will be partial control of theory and problems in mid-April. The Virtual Campus will upload material to review the notes collected in class.
The class of problems will be devoted to the resolution oriented to some problems proposed. Students' participation in the problem classes will be especially encouraged.
Practical classes will introduce the use of R software with statistical applications. You will see descriptive and inferential methodologies. You will have to deliver some practical work.
The proposed teaching methodology may experience some modifications depending on the restrictions to face-to-face activities enforced by health authorities.
