Complex Surveys

Incorporates the use of R subroutines in the analysis of surveys Realistically large, but not technologically inaccessible, data sets are showcased to illustrate the need for and utility of the R software system.

Klappentext

Survey analysis remains the bread-and-butter of sociological research. Highlighting three main areas of interest-calibration estimators, two-phase designs, and fitting of regression models to survey data-Complex Surveys is the first book to describe the use of R in survey analysis in order to meticulously demonstrate new and efficient analyses of survey research methods in the health and social sciences. Written for applied statisticians and sophisticated users of statistics in the health and social sciences, the text employs large data sets throughout to illustrate the need for, and utility of, the R software system.
