Editor's Notes and Comments:
Product Description:
Social scientists are often interested in studying differences in groups, such as gender or race differences in attitudes, buying behaviors, or socioeconomic characteristics. When the researcher seeks to estimate group differences through the use of independent variables that are qualitative (i.e., measured at only the nominal level), dummy variables will allow the researcher to represent information about group membership in quantitative terms without imposing unrealistic measurement assumptions on the categorical variables. Beginning with the simplest model, Hardy probes the use of dummy variable regression in increasingly complex specifications, exploring issues such as: interaction, heteroscedasticity, multiple comparisons and significance testing, the use of effects or contrast coding, testing for curvilinearity, and estimating a piecewise linear regression.

Like most of the books in the Sage Quantitative Applications in the Social Sciences, this is clearly written and understandable. This is one of those rare statistics texts that is readable and useful. If you need to understand or use dummy variables in regression, this book will save you enormous amounts of time and frustration. Strongly recommended.
Rated by buyers -
This book saved my life! It provided clear explanations and great examples of how to use and interpret regressions with dummy variables. I don't know how I would have passed without it. An extra bonus for people interested in strat--the examples deal with inequality.
