Nonparametric Regression with Complex Survey Data

Raymond Chambers, Alan H. Dorfman, and M. Sverchkov


The problem considered here is one familiar to analysts carrying out exploratory data analysis (EDA) of data obtained via a complex sample survey design. How does one adjust for the effects, if any, induced by the method of sampling used in the survey when applying EDA methods to these data? In particular, are adjustments to standard EDA methods necessary when the analyst's objective is identification of "interesting" population (rather than sample) structures?
