A Practical Guide to Age-Period-Cohort Analysis

The Identification Problem and Beyond

• Gebundenes Buch

Produktbeschreibung

A popular and efficient tool to analyze grouped data of a certain event, APC analysis is used in a range of application areas, including public health, social science, demography, and economics. This book first describes the basic graphic presentation and modeling of APC data using R. Taking a more theoretical point of view, it then presents various methods for addressing the complex identification problem. Appendices cover the necessary background material.
