时空高斯模型的分形与光滑性

Fractal and Smoothness Properties of Space-Time Gaussian Models

Yun Xue, Yimin Xiao

摘要:

时空模型在统计推断和许多应用领域中有着广泛的应用。在这种情况下,利益往往是在样本表面的分形性质和在给定的位置在给定的方向上的空间表面的变化率。本文应用Yaglom(1957)的理论,构造了一大类具有平稳增量的时空高斯模型,建立了预测误差的界,并确定了这类高斯模型的光滑性和分形性。我们的结果可以直接应用于分析Cressie和Huang(1999),Gneiting(2002)和Stein(2005)分别提出的平稳时空模型。

英文摘要:

Spatio-temporal models are widely used for inference in statistics and many applied areas. In such contexts interests are often in the fractal nature of the sample surfaces and in the rate of change of the spatial surface at a given location in a given direction. In this paper we apply the theory of Yaglom (1957) to construct a large class of space-time Gaussian models with stationary increments, establish bounds on the prediction errors and determine the smoothness properties and fractal properties of this class of Gaussian models. Our results can be applied directly to analyze the stationary space-time models introduced by Cressie and Huang (1999), Gneiting (2002) and Stein (2005), respectively.
