英文文献摘要：
The implications of ignoring potential spatial dependence in county-level yield data are discussed. Spatial dependence in a county-level yield data set is identified and methods for correcting the dependence via spatial weighting matrices and generalized least squares regression are performed. The paper also examines how the spatial dependence declines as the distance between observations increases.

讨论了在县级产量数据中忽略潜在空间依赖的影响。识别了县级产量数据集的空间依赖关系，并利用空间加权矩阵和广义最小二乘回归对依赖关系进行了修正。本文还研究了空间依赖性如何随着观测距离的增加而下降。
