Estimating Spatial Autocorrelation with Sampled Network Data
NetworkDataAnalysis Paired Maximum Likelihood Estimator
2016/1/26
Spatial autocorrelation is a parameter of importance for network data analysis. To estimate spatial autocorrelation, maximum likelihood has been popularly used. However, its rigorous implementation re...
AN ALGORITHM ABOUT ASSOCIATION RULE MINING BASED ON SPATIAL AUTOCORRELATION
Geographical information science Statistical analysis Data mining Geography Spatial association rule spatial auto-correlation
2015/12/23
Most spatial data in GIS are not independent, they have high autocorrelation. For example, temperatures of nearby locations are often related. Most of the spatial association rule mining algorithms de...
Assessing the significance of global and local correlations under spatial autocorrelation;a nonparametric approach
Geostatistics Monte-Carlo methods Resampling Spatial autocorrelation Spatial statistics Variogram

In this paper we present a method to assess the significance of the correlation coefficient when at least one of the variables is spatially autocorrelated. The standard test assumes independence of th...
FEATURE MODELLING OF HIGH RESOLUTION REMOTE SENSING IMAGES CONSIDERING SPATIAL AUTOCORRELATION
high resolution feature modelling spatial autocorrelation segmentation

To deal with the problem of spectral variability in high resolution satellite images, this paper focuses on the analysis and modelling of spatial autocorrelation feature. The semivariograms are used t...
小麦多年产量空间变异与空间关联分析（Spatial Autocorrelation Analysis of Wheat Yield over Five Years）
小麦产量 空间相关性 自相关
2010/12/28
利用全局空间统计方法Moran’s I和局部空间统计方法LISA研究了小汤山国家精准农业基地2001~2006年小麦产量及两种气候模式下产量的空间变异和空间关联。研究结果表明，不同年份产量及气候模式下均存在极显著的空间自相关；全局和局部空间自相关分析表明，试验地块的东北部、西部和南部区域存在极显著的空间自相关，但东北部和西部区域在不同的气候模式下产量变化幅度较大，而南部区域产量趋于稳定。
