Spatiotemporal Kriging with External Drift
In statistics it is often assumed that sample observations are independent. But sometimes in practice, observations are somehow dependent on each other. Spatiotemporal data are dependent data which their correlation is due to their spatiotemporal locations.Spatiotemporal models arise whenever data are collected across bothtime and space. Therefore such models have to be analyzed in termsof thei...
متن کاملGradient-Enhanced Universal Kriging for Uncertainty Propagation
In this work, we investigate the issue of providing a statistical model for the response of a computer model-described nuclear engineering system, for use in uncertainty propagation. The motivation behind our approach is the need for providing an uncertainty assessment even in the circumstances where only a few samples are available. Building on our recent work in using a regression approach wi...

متن کاملNumerical Aspects of the Universal Kriging Method for Hydrological Applications
Many hydrological variables usually show the presence of spatial drifts. Most often they are accounted for by either universal or residual kriging and usually assuming low order polynomials. The Universal Kriging matrix ( M ), which includes in it the values of the polynomials at data locations (matrix F ), in some cases may have a too large condition number and can even be nearly singular due ...
متن کاملSpatiotemporal Visualization of the Tongue Surface using Ultrasound and Kriging
Analyzing the motion of the tongue surface provides valuable information about speech and swallowing. To analyze this motion, two-dimensional ultrasound images are acquired at video frame rates, and the tongue surface is automatically extracted and tracked. Further processing and statistical analysis of the extracted contours is made difficult by: 1) arbitrary spatial shifts and data loss resul...
