Course Rationale

The aim of this course is to introduce students to the science of model building and their use. In model building students will use a set of quantitative parameters to construct and test mathematical models of the real world by using regression analysis and time series. Students develop problem solving and data analysis skills by using statistical software to analyze real data.

The course is constructed in such a way as to satisfy the requirements in Applied Statistics of SOA.

Course Description

This course biulds on the applied aspects of Statistics I. It is primarily concerned with the construction of regression and time series models relevant to econometric modelling.

Assessment is designed to encourage students to work continuously with the course materials. Active learning will be achieved through marked assignments supplemented by problem papers, allowing continuous feedback and guidance on problem solving techniques in tutorials and lectures. Assessment will be based on the marked assignments and in-course tests followed by a final examination based on the whole course. Software used in the actuarial field will be incorporated in the course so that students develop practical skills
