Short Description

This course will provide the conceptual foundations needed to develop models tailored to specific questions and data in order to update existing knowledge. Emphasis will be on Bayesian approaches, using existing knowledge to build models for the data generation process and to define plausible parameter distributions. Students will be exposed to different computational methods to obtain parameter estimates and to assess model fit. Throughout the class, students will be made aware of to the importance of considering causal structures in model formulation and interpretation.

Timetable

This course is made up of lectures and practical classes in semester 2. 

Requirements of Entry

None

Assessment

Assessment will consist of laboratory reports 1-7 (testing ILO 1-7, respectively), only 5 of which will be summative (50%) and a final project (50%).

 Lab reports consists on short exercises and questions (3 to 5 items per report). The final project involves the analysis of a data set to answer specific research questions (tests ILOs 1-7). 2000 words.

Are reassessment opportunities available for all summative assessments? No

The students will be provided with the option to submit only 8 out of ten practical reports for this course. If more are submitted, they will be marked and can be used as formative assessment by the students. The best 8 marks will count towards their final mark. This flexibility is offered so that deadlines can be adhered to, but it means that no re-assessment opportunities will be offered for continuous assessment. The final project will be reassessed if necessary as per university regulations.

Course Aims

The aim of the course is to provide the student with the fundamentals of model formulation, bayesian data analysis, and causal inference.

Intended Learning Outcomes of Course

By the end of this course students will be able to:

 

1. Critically discuss key differences between a Bayesian and frequentist approach

2. Understand critically of how prior information is used in a Bayesian approach and their appropriate use

3. Understand and apply the concept of Markov Chain Monte Carlo techniques 

4. Critically discuss the importance of causal structures in model formulation and analysis

5. Write simple programs in JAGS and Stan

6. Critically evaluate and apply appropriate solutions to issues with model fit.

7. Build and interpret simple causal models using directed acyclic graphs

Minimum Requirement for Award of Credits

Students must submit at least 75% by weight of the components (including examinations) of the course's summative assessment.
