Using universal kriging to improve neighborhood physical disorder measurement. [PDF]
Sociol Methods Res, 2020 Ordinary kriging, a spatial interpolation technique, is commonly used in social sciences to estimate neighborhood attributes such as physical disorder. Universal kriging, developed and used in physical sciences, extends ordinary kriging by supplementing the spatial model with additional covariates.

Universal kriging for spatio‐temporal data
Mathematical Modelling and Analysis, 2003 In this article we have used wide applicable classes of spatio‐temporal nonseparable and separable covariance models. One of the objectives of this paper is to furnish a possibility how to avoid the usage of complicated covariance functions.

Universal Kriging Prediction of Line-of-Sight Microwave Fading [PDF]
IEEE Access, 2020 Prediction of the severity of multipath fading is fundamental to the design of point-to-point terrestrial fixed microwave links at frequencies below 10 GHz, but error in this prediction may be significant in countries such as Australia, not represented ...

Universal Kriging Prediction of nonstationary Spatial Stochastic Process [PDF]
المجلة العراقية للعلوم الاحصائية, 2010 Spatial Stochastic processes are often divided into two types that are stationary spatial stochastic processes and other nonstationary. In most practical applications the processes are nonstationary .Prediction of these processes are performed by ...

Enhanced universal kriging for transformed input parameter spaces
Probabilistic Engineering Mechanics, 2023 With computational models becoming more expensive and complex, surrogate models have gained increasing attention in many scientific disciplines and are often necessary to conduct sensitivity studies, parameter optimization etc. In the scientific discipline of uncertainty quantification (UQ), model input quantities are often described by probability ...

Grade control in a quartz deposit using universal fuzzy kriging
Dyna, 2013 Adaptamos el método universal de predicción por Krigeado a contextos con datos inciertos o imprecisos. Empleando la teoría de conjuntos difusos, desarrollamos un Krigeado difuso niversal que utilizamos para estimar tipos de calidades en un depósito de ...
