本文探讨了使用皮尔逊积矩相关系数和斯皮尔曼等级相关系数的地图数据，空间相关。研究表明，在这种情况下，标准估计低估了皮尔逊系数的真实抽样方差。Clifford和Richardson的“有效样本量”解决这个问题的描述，实施过程中考虑的方法，和性能的技术检查。该方法还用于调整斯皮尔曼检验。给出了两个应用，并将Clifford和Richardson的方法与数据“预白化”方法进行了对比。
The paper examines the use of the Pearson product moment correlation coefficient and the Spearman rank correlation coefficient on map data that are spatially correlated. Research has shown that in this case standard estimators underestimate the true sampling variance of the Pearson coefficient. The Clifford and Richardson “effective sample size” solution to this problem is described, methods for implementing the procedure are considered, and properties of the technique examined. The method is also used to adjust the Spearman test. Two applications are given and the method of Clifford and Richardson contrasted with the method of data “prewhitening.”
