Expansions and Asymptotics for Statistics

Asymptotic methods provide important tools for approximating and analysing functions that arise in probability and statistics. Moreover, the conclusions of asymptotic analysis often supplement the conclusions obtained by numerical methods. Providing a broad toolkit of analytical methods, Expansions and Asymptotics for Statistics shows how asymptotics, when coupled with numerical methods, becomes a powerful way to acquire a deeper understanding of the techniques used in probability and statistics.

In this chapter we show you what macroeconomics is about by looking at some of the big questions that macroeconomists ask: Why do some countries enjoy a standard of living many times greater than others? How does growth in productivity evolve over time? Why does the economy fluctuate between expansions and contractions? What impact do changes in interest rates or in oil prices have upon the economy?
