In this talk we consider the maximum absolute value in the autocorrelation spectrum (not considering the zero point) of balanced Boolean function. The long-standing open question in this area is to ob...
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...

Based on the self-characteristic of digital watermarking techniques and the multi-statistic theory, this paper makes a research on the watermark autocorrelation detection. First, the setting of detect...
Assessing the significance of global and local correlations under spatial autocorrelation;a nonparametric approach
Geostatistics Monte-Carlo methods Resampling Spatial autocorrelation Spatial statistics Variogram
2015/8/21
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...

Abstract: We propose a method based on probabilistic arguments to study the convexity of the autocorrelation function of processes associated with a single server queue. To illustrate the power of the...
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。
