The purpose of this series of documents is to introduce the reader to inequality studies, with an emphasis on Theil's T Statistic as a measure of wage and income inequality.
|Non-technical introduction briefly describes inequality studies and reviews several leading inequality measures.
|A Nearly Painless Guide to Computing Theil's T Statistic
|Brief example with an emphasis on constructing research questions and using a spreadsheet to conduct analysis
|Using Theil's T Statistic: U.S. Income Inequality by County
|Extended example with an emphasis on data retrieval, data processing, and presentation.
|The Theoretical Basics of Popular Inequality Measures
|This document explores several inequality measures used broadly in the literature, with a special emphasis on how to compute Theil's T statistic.
More technical presentations that describe the use of Theil's T statistic to measure inequality in aggregated and hierarchical data sets.
|The Mechanics and Logic of the Theil Statistic (Español)
|Includes the origins (Shannon's information measure), and the mathematical properties (decomposition) of the Theil Statistic.
|Mechanics to Calculate the Theil and use of Programs and Macros (Español)
|Includes data discussion and a guide to calculate the between-groups and within-groups component, and the total Theil's T-statistic in excel.
