ST416: Advanced Topics in Biostatistics

Professor David Wild
∗∗∗ Please note that this module will not be running in the 2017/18 academic year. ∗∗∗

3 lectures per week over 10 weeks. This module will run in Term 2.

Assessment: 100% by 2 hour examination

Prerequisite(s): ST111/112 Probability A and B, ST218/219 Mathematical Statistics A&B, basic computing literacy (R, Matlab,...)

Aims: This module presents the application of methods from probability, statistical theory, and stochastic processes to problems of interest to bioinformaticians and systems biologists, mainly in the area of biosequence analysis.

Objectives: It is expected that students who have taken the module will have mastered the basic set of ideas required in order to carry out further research in bioinformatics methods and algorithms, or to apply these ideas in biomedical applications.


• Single DNA sequence analysis:
- Signal modelling
- Pattern analysis

• Multiple DNA/protein sequence analysis:
