Comment: Getting into Space with a Weight Problem
本文讨论在分析调查数据时如何处理复杂设计，重点比较直接使用权重和基于空间模型的聚类方法，并介绍随机偏微分方程（SPDE）的空间建模方法。
This article will focus its discussion on accounting for the complex design when analyzing survey data, and on spatial modeling. With respect to the former, this article considers two approaches: direct use of the weights, and a model-based approach using a spatial model to acknowledge clustering. With respect to spatial modeling this article describes, the stochastic partial differential equations (SPDEs; Lindgren et al. 2011) approach to modeling.
