Complex Surveys

A Guide to Analysis Using R

• Broschiertes Buch

Produktbeschreibung

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.
