The middle class is often viewed as the heart of American society, the key to the country's democracy and prosperity. Most Americans believe they belong to this group, and few politicians can hope to be elected without promising to serve the middle class. Yet today the American middle class is increasingly seen as under threat. In The American Middle Class: A Cultural History, Lawrence R. Samuel charts the rise and fall of this most definitive American population, from its triumphant emergence in the post-World War II years to the struggles of the present day.

They combine and up- date most of the material from their widely used earlier work, An Introduction to Regression Graphics, and Weisberg's Applied Linear Regression; incorporate the latest in statistical graphics, computing, and regression models; and wind up with a modern, fully integrated approach to one of the most important tools of data analysis.In 23 co 410 0$aWiley Series in Probability and Statistics 606 $aRegression analysis 606 $aMultivariate analysis 615 0$aRegression analysis. 615 0$aMultivariate analysis. 676 $a519.5 676 $a519.536 700 $aCook$b R.
