Statistical Modeling for Spatio-Temporal Data From Stochastic Convection-Diffusion Processes
随机对流扩散过程时空数据的统计建模
This article proposes a physical-statistical modeling approach for spatio-temporal data arising from a class of stochastic convection-diffusion processes. Such processes are widely found in scientific and engineering applications where fundamental physics imposes critical constraints on how data can be modeled and how models should be interpreted. The idea of spectrum decomposition is employed to approximate a physical spatio-temporal process by the linear combination of…
