**Valid from:** Spring 2014**Decided by:** FN1/Anders Gustafsson**Date of establishment:** 2014-01-13

**Division:** Mathematical Statistics**Course type:** Course given jointly for second and third cycle**The course is also given at second-cycle level with course code:** FMS091**Teaching language:** English

The aim is that doctoral student shall gain proficiency with modern computer intensive statistical methods and use these to estimate quantities and parameters in complex models that arise in different applications (e.g. economics, signal processing, biology, climate, and environmental statistics). The purpose of the course is to give the doctoral student tools and knowledge to handle complex statistical problems and models in order to be able to use these in the doctoral student's own research. Further, the doctoral student should be able to assess the uncertainty of these estimates. The main aim lies in enhancing the scope of statistical problems that the doctoral student will be able to solve.

*Knowledge and Understanding*

For a passing grade the doctoral student must

- Be able to describe fundamental principles of Monte Carlo integration and random variable generation.
- Be able to explain and use the concept of statistical uncertainty from a frequentist perspective as well as from a Bayesian perspective.
- Be able to describe fundamental principles of parametric and non-parametric resampling.

*Competences and Skills*

For a passing grade the doctoral student must

- Given a stochastic model and problem formulation, be able to choose relevant quantities in a way that permits approximation using Monte Carlo methods.
- Given a (possibly multivariate) probability distribution, be able to suggest and implement in a computer program, a method for generation of random variables from this distribution.
- Given a large number of generated random variables from a probability distribution, be able to approximate relevant probabilities and expectations as well as estimate the uncertainty in the approximated quantities.
- Given a model description and a statistical problem, be able to suggest a simple permutation test and implement it in a computer program.
- Given a model description and a statistical problem, be able to suggest a resampling procedure and implement it in a computer program.
- Be able to present the course of action taken and conclusions drawn in the solution of a given statistical problem.

*Judgement and Approach*

For a passing grade the doctoral student must Be able to identify and problemise the possibilities and limitations of statistical inference.
