Spatial analysis and prediction of Curonian lagoon data with Gstat
Mathematical Modelling and Analysis, 2004 The typical goal of geostatistical analysis is to interpolate values of variable under consideration at unobserved locations using data on observed locations because it is not feasible to gather all data of the observations in the study area.

Graph Variogram: A novel tool to measure spatial stationarity
, 2018 Irregularly sampling a spatially stationary random field does not yield a graph stationary signal in general. Based on this observation, we build a definition of graph stationarity based on intrinsic stationarity, a less restrictive definition of ...

Environmetrics, Volume 37, Issue 1, January 2026.ABSTRACT Classic Bayesian methods with complex environmental models are frequently infeasible due to an intractable likelihood. Simulation‐based inference methods, such as neural posterior estimation, calculate posteriors without accessing a likelihood function by leveraging the fact that data can be quickly simulated from the model, but converge ...

Influência do Tipo de Amostragem na Estimativa de Volume de Madeira de Eucalipto por Krigagem
Floresta e AmbienteRESUMO O objetivo da pesquisa foi verificar se a estimativa do volume individual de madeira por árvore realizada pela krigagem é influenciada pelo tipo de amostragem. Um povoamento com 1.875 árvores de eucalipto foi demarcado em um plano cartesiano (X, Y)

A disposition of interpolation techniques [PDF]
A large collection of interpolation techniques is available for application in environmental research. To help environmental scientists in choosing an appropriate technique a disposition is made, based on 1) applicability in space, time and space-time, 2)

Measuring Spatial Dependence with Semivariograms
Bulletin (Kansas Geological Survey), 1977 The semivariogram is a measure of statistical dependence and is closely related to the autocorrelogram. It is particularly suitable for analysis of spatial functions that describe natural phenomena characterized by a geographic distribution and variations which arc in part continuous and in part stochastic.
