  1. The method for retaining sampled units in successive sampling survey for changed probability of selection is introduced. for pps sampling design, a model - design unbiased predictor for the total of a variable for the target population is proposed, and the optimum matching ratio for the predictor under the assumption of unchanged population is calculated. for rhc sampling design, the equation that the optimum matching ration satisfies is given

    介紹了連續抽樣中概率發生變化時保留樣本的方法。對于有放回的pps抽樣,在假設的超總體模型之下提出了總體變量總值的模型設計無偏預報量,並計算了總體不變時保留樣本的最優匹配比。對于無放回的rhc抽樣,給出了最優匹配比滿足的方程。
