Abstract:
|
Spatial data has been progressively observed and recorded in various forms in numerous applications. Symbolic data analysis (SDA) is an approach to analyzing massive or complex data aggregated into multi-valued forms, such as intervals, histograms, and lists. In this paper, we focus on non-stationary spatial interval-valued data (SIVD). We propose kriging with external drift (KED) methodologies for spatial prediction of SIVD with scalar and interval-valued covariates. A simulation study is performed to compare prediction performance. We illustrate the utility of the proposed methods by applying them to real-world SIVD dataset.
