At the start of this course the student should have acquired the following competences:

an active knowledge of

an active knowledge of

- Dutch

Knowledge of basic concepts of probability theory: random variable, distribution, density, characteristic function, expectation, covariance, covariance matrix, notions of convergence ...: univariate as well as multivariate.

Knowledge of basic concepts and notations of measure theory.

Students are able to work with classical well known distributions. For a generally defined distribution they can compute and interpret typical properties such as expectation, etc.

- you can find an estimator for an unknown parameter of a given parametric model and check the main properties of this estimator ;
- you can assess the quality of an estimator and compare an estimator with other estimators ;
- you can conduct inference concerning the parameter of a specific 1-parametric model, i.e. construct a confidence interval and perform hypothesis tests ;
- you can identify which hypothesis test should be used given a concrete situation and you can perform this test and draw an appropriate conclusion ;
- you can fit an appropriate linear model given a specific situation and you are aware of the model assumptions and know how to check them ;
- you can perform hypothesis tests concerning linear models to answer specific questions (e.g. is there a significant difference between several groups; are two variables connected; ...) ;
- you have a good knowledge of R to apply all aforementioned methods on concrete data sets. You can draw correct conclusions based on R output.

- We define the basic concepts of statistical models: statistical models, likelihood function, parametric model, non-parametric model, random sample, empirical distribution, …
- We define the basic concepts of statistics: statistic, image space, sufficient statistic, complete statistic, minimal sufficient statistic, … and we discuss various examples of widely used statistics (sample mean, sample variance, order statistics, rank statistics, …)
- We discuss parameter estimation within a parametric model: we study methods to find an estimator and to check its properties.
- We discuss the construction of a confidence interval for an unknown parameter.
- We study the mechanism of hypothesis tests about a parameter. We introduce some specific hypothesis tests and we discuss which test is most appropriate under which circumstances.
- We introduce the linear model. We discuss parameter estimation and the construction of confidence intervals and hypothesis tests.
- We use the statistical software package R to apply a data analysis based on statistical methods.
