Ageing epidemiology is the study of the health of an ageing population. It is a very active area of research in epidemiology, but has its own issues, which has led to the development of methodology specific to the area. This book covers all the essential statistical tools for analysing cross sectional and longitudinal epidemiological data for ageing research. It has lots of worked examples using real data to illustrate the methods, and Stata and R code for all the examples.
