Assessing Inequality

Assessing Inequality

May 2010 | 160 pages | SAGE Publications, Inc
This text reviews a set of widely used summary inequality measures, and the lesser known relative distribution method provides the basic rationale behind each and discusses their interconnections. It also introduces model-based decomposition of inequality over time using quantile regression. This approach enables researchers to estimate two different contributions to changes in inequality between two time points.

Key Features:

- Clear statistical explanations provide fundamental statistical basis for understanding the new modeling framework

- Straightforward empirical examples reinforce statistical knowledge and ready-to-use procedures

- Multiple approaches to assessing inequality are introduced by starting with the basic distributional property and providing connections among approaches

This supplementary text is appropriate for any graduate-level, intermediate, or advanced statistics course across the social and behavioural sciences, as well as individual researchers.

SAGE Research Methods is a research methods tool created to help researchers, faculty and students with their research projects. SAGE Research Methods links over 175,000 pages of SAGE’s renowned book, journal and reference content with truly advanced search and discovery tools. Researchers can explore methods concepts to help them design research projects, understand particular methods or identify a new method, conduct their research, and write up their findings. Since SAGE Research Methods focuses on methodology rather than disciplines, it can be used across the social sciences, health sciences, and more.
