On Survey Sample Designs for Consumer Price Indexes

Alan H. Dorfman, Sylvia G. Leaver, Janice Lent, and Edward Wegman

Then, through simulation, we compare the degree to which accurate estimation of the population targets is achieved by a variety of commonly used sampling methods and different index estimators. Of particular interest is the comparison of probability and judgmental approaches to sampling.
