Course unit details:
|Unit level||FHEQ level 7 – master's degree or fourth year of an integrated master's degree|
|Teaching period(s)||Semester 1|
|Offered by||Department of Mathematics|
|Available as a free choice unit?||No|
Computers are an invaluable tool to modern statisticians. The increasing power of computers has greatly increased the scope of inferential methods and the type of models which can be analysed. This has led to the development of a number of computationally intensive statistical methods, many of which will be introduced in this course.
|Unit title||Unit code||Requirement type||Description|
Students are not permitted to take more than one of MATH38091 or MATH48091 for credit in the same or different undergraduate year.
Students are not permitted to take MATH48091 and MATH68091for credit in an undergraduate programme and then a postgraduate programme.
Note that MATH68091 is an example of an enhanced level 3 module as it includes all the material from MATH38091
When a student has taken level 3 modules which are enhanced to produce level 6 modules on an MSc programme taken within the School of Mathematics, then they are limited to a maximum of two such modules (with no alternative arrangements available otherwise)
To introduce the student to computational statistics, both the underlying theory and the practical applications.
On successful completion of this course unit students will be able to:
- construct algorithms to simulate random observations from probability distributions using a variety of methods and explain mathematically why they work;
- construct and derive the statistical properties of Monte Carlo estimators, as well as alternatives which seek to reduce variance;
- apply the bootstrap to assign measures of accuracy to sample estimates and to derive their statistical properties analytically in some simple cases;
- recognise a non-linear regression model and be able to formulate the Gauss-Newton algorithm to find the parameter estimates from data;
- use the EM algorithm to find maximum likelihood estimators of parameters in some given contexts when we have incomplete sample information;
- implement the methodology discussed in the module (and also carry out simple simulation studies) on a computer using the statistical software R. To present informatively and discursively the results of computations.
- Introduction 
- Simulating random variables: inversion of the cdf; rejection sampling; transformations; ratio of uniforms. 
- Monte Carlo integration 
- Variance Reduction: importance sampling; control variates. 
- Nonparametric bootstrap methods; the Jackknife. 
- Nonlinear regression: model specification; least squares estimation; Gauss-Newton algorithm. 
- EM algorithm: data augmentation; the multinomial model; mixture distributions, censored data, Monte-Carlo EM. 
- Three pieces of coursework each worth 16.67% : 50%
- End of semester written examination: 50%
Feedback tutorials will provide an opportunity for students' work to be discussed and provide feedback on their understanding. Coursework also provides an opportunity for students to receive feedback. Students can also get feedback on their understanding directly from the lecturer, for example during the lecturer's office hour.
