Econometrics and Data Analysis for Developing Countries
Getting accurate data on less developed countries has created great problems for studying these areas. Yet until recently students of development economics have relied on standard econometrics texts, which assume a Western context. Econometrics and Data Analysis for Developing Countries solves this problem. It will be essential reading for all advanced students of development economics.
Regression Methods in Biostatistics

Theprimarybiostatisticaltoolsinmodernmedicalresearcharesingle-outcome, multiple-predictor methods: multiple linear regression for continuous o- comes, logistic regression for binary outcomes, and the Cox proportional h- ardsmodelfortime-to-eventoutcomes. Morerecently,generalizedlinearm- els and regression methods for repeated outcomes have come into widespread use in the medical research literature. Applying these methods and interpr- ing the results requires some introduction. However, introductory statistics courses have no time to spend on such topics and hence they are often r- egated to a third or fourth course in a sequence. Books tend to have either very brief coverage or to be treatments of a single topic and more theoretical than the typical researcher wants or needs. Our goal in writing this book was to provide an accessible introduction to multipredictor methods, emphasizing their proper use and interpretation. We feel strongly that this can only be accomplished by illustrating the te- niques using a variety of real datasets. We have incorporated as little theory as feasible. Further, we have tried to keep the book relatively short and to the point. Our hope in doing so is that the important issues and similarities between the methods, rather than their di?erences, will come through. We hope this book will be attractive to medical researchers needing familiarity with these methods and to students studying statistics who would like to see them applied to real data.
The Dueling Loops of the Political Powerplace: Why Progressives Are Stymied and How They Can Find Their Way Again
Contrary to popular myth, it is possible for progressives to take an analytical approach to solving difficult social problems and win. Using the sustainability problem as a running example, this book demonstrates how. The same key tool Limits to Growth used, simulation modeling, is applied. However, unlike Limits to Growth this book explores the social side of the problem, rather than the technical side, to find the fundamental cause of the very strong change resistance civilization has encountered. The root cause turns out to lie in a surprisingly simple social structure called the Dueling Loops of the Political Powerplace. The book explains in laymanâÂÂs terms how the Dueling Loops model works, where the intuitively attractive but low leverage point is that progressives are presently pushing on, and where the high leverage points are they must push on instead. The end result is a whole new way of thwinking. For further information on this book and project, please see thwink.org.
