On the efficiency of randomized PPS sampling with an application to the Producer Price Index

6-3-2009 09:45

This paper examines the efficiency of the Horvitz-Thompson estimator from a systematic probability proportional to size sample drawn from a randomly ordered list. Moreover, the efficiency is compared with that of an ordinary ratio estimator. The results are demonstrated by means of a simulation study with Dutch data on the Producer Price Index. The discussion on the efficiency includes a comparison with rejected Poisson sampling.
