信息选择对空间过程参数估计的影响

The effect of Informative Selection on the estimation of parameters related to Spatial Processes

Daniel Bonnery, Francesco Pantalone, M. Giovanna Ranalli

摘要:

本文将信息选择、总体分布和样本分布的概念推广到空间过程中。这些概念首先定义在这样的背景下,其中感兴趣的随机过程的输出由总体中每个个体的独立且同分布的实现组成。它已被证明,信息选择诱导随机依赖的实现所选择的单位。在空间过程的背景下,“人口”是一个连续的空间,人口的两个不同要素的实现不是独立的。我们展示了如何信息选择可能会导致不同的依赖性之间的选定单位和样本分布如何不同的总体分布。

英文摘要:

This paper extends the concept of informative selection, population distribution and sample distribution to a spatial process context. These notions were first defined in a context where the output of the random process of interest consists of independent and identically distributed realisations for each individual of a population. It has been showed that informative selection was inducing a stochastic dependence among realisations on the selected units. In the context of spatial processes, the "population" is a continuous space and realisations for two different elements of the population are not independent. We show how informative selection may induce a different dependence among selected units and how the sample distribution differs from the population distribution.
