定义小区域估计的样本设计

Defining the sample designs for small area estimation

Piero Demetrio Falorsi, Stefano Falorsi, Vincenzo Nardelli, Paolo Righi

摘要:

本文描述了一个适当的统计设置,用于定义小面积估计问题的抽样设计。这个问题往往只能通过间接估计来处理,使用的是来自不同地区或不同时间的有关变量的值,从而增加了样本量。然而,让我们假设域指标变量可用于总体中的每个单元。在这种情况下,我们可以定义一个固定小区域样本大小的抽样设计,从而显着提高小区域估计的准确性。我们可以将这一抽样战略应用于商业调查,在商业调查中,领域指标变量可以在商业登记册中找到,甚至可以在家庭调查中找到地理领域的领域指标变量。

英文摘要:

The paper delineates a proper statistical setting for defining the sampling design for a small area estimation problem. This problem is often treated only via indirect estimation using the values of the variable of interest also from different areas or different times, thus increasing the sample size. However, let us suppose the domain indicator variables are available for each unit in the population. In that case, we can define a sampling design that fixes the small-area samples sizes, thereby significantly increasing the accuracy of the small area estimates. We can apply this sampling strategy to business surveys, where the domain indicator variables are available in the business register and even household surveys, where we can have the domain indicator variables for the geographical domains.
