Unit value:

Year of study:
Year 1
Taught in:
Full Year
The purpose of this course is to train students in the basic techniques of Mathematics and Statistics. The course is designed for both students with little prior knowledge of the topics, and students who have not studied these disciplines for a long time. By the end of the year students should be familiar with the techniques most commonly used in economic analysis and be capable of undertaking further study of advanced economic techniques. Topics include: calculus; optimisation; linear algebra; descriptive statistics; estimation; hypothesis testing; regression analysis; and index numbers.
