Nonparametric Estimation of Crop Yield Distributions: Implications for Rating Group‐Risk Crop Insurance Contracts
用非参数密度估计方法评估县级作物产量分布，并讨论其对区域产量作物保险合同评级的影响，为小麦和大麦的产量风险测度和保费率计算提供依据。
Abstract We use nonparametric density estimation procedures to evaluate county‐level crop yield distributions. Implications for rating area‐yield crop insurance contracts are discussed. The procedures developed are used to measure yield risk and calculate insurance premium rates for wheat and barley in the 1995–96 Group Risk Program.
