A Sampling Strategy for Successive Sampling on Two Occasions with the Data Recalled

We consider a kind of successive sampling on two occasions, in which the data in the last time can be recalled from the survey questionaire in this time. The data in the last time is good as auxiliary data for estimating the characteristics of population in this time. We propose a sampling strategy for this kind of successive sampling and present a simulation study with the data of sample survey of fertility and birth control in China in 1988.
