Type: Cycle 39 - Mandatory Courses
Aims: to explore a number of statistical principles. To consider the nature of statistical parameters, the different viewpoints of Bayesian and Frequentist approaches and their relationship with the given statistical principles. To introduce the idea of inference as a statistical decision problem. To introduce important aspects of statistical modelling, including model selection, various extensions to likelihood theory and its link with alternative approaches, to master asymptotic arguments.
Learning outcomes: An appreciation for the complexity of statistical inference, recognition of its inherent subjectivity and the role of expert judgement, the ability to critique familiar inference methods, knowledge of the key choices that must be made, and scepticism about apparently simple answers to difficult questions.
Final exam: written exam for each modulus.
Course contents
The course is articulated in two moduli, with final assessment for each of the moduli.

- Statistics, Sufficiency, and Completeness
- Efficiency of estimators, optimality of tests
- The Bayesian approach, exchangeability, Dirichlet process
Module 2: Beyond conventional statistical inference (prof. M.V. Feser)
