Heteroskedasticity in Regression
Detection and Correction



August 2013 | 112 pages | SAGE Publications, Inc

This volume covers the commonly ignored topic of heteroskedasticity (unequal error variances) in regression analyses and provides a practical guide for how to proceed in terms of testing and correction. Emphasizing how to apply diagnostic tests and corrections for heteroskedasticity in actual data analyses, the book offers three approaches for dealing with heteroskedasticity:

  • variance-stabilizing transformations of the dependent variable;
  • calculating robust standard errors, or heteroskedasticity-consistent standard errors; and
  • generalized least squares estimation coefficients and standard errors.

The detection and correction of heteroskedasticity is illustrated with three examples that vary in terms of sample size and the types of units analyzed (individuals, households, U.S. states). Intended as a supplementary text for graduate-level courses and a primer for quantitative researchers, the book fills the gap between the limited coverage of heteroskedasticity provided in applied regression textbooks and the more theoretical statistical treatment in advanced econometrics textbooks.

Language of the book is easily understanable for undergraduate students. The way of teaching is well-organized. Limited sources on this issue makes the book extremly valuable.

Quite important book as it clarifies the phenomenon of heteroscedasticity beyond the statements found in usual teaching books for statistics.
It contains many examples, which helps the reader to understand the concept.

However, it would have been good to implement practical advices for dealing with heteroscedasticity in SPSS or R, or in other words: with the book, the reader is able to understand the concept, but he is not fully able to deal with it in statistical programs.

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.

With SAGE Research Methods, researchers can explore their chosen method across the depth and breadth of content, expanding or refining their search as needed; read online, print, or email full-text content; utilize suggested related methods and links to related authors from SAGE Research Methods' robust library and unique features; and even share their own collections of content through Methods Lists. SAGE Research Methods contains content from over 720 books, dictionaries, encyclopedias, and handbooks, the entire “Little Green Book,” and "Little Blue Book” series, two Major Works collating a selection of journal articles, and specially commissioned videos.
