非线性生殖分散模型（NRDM, Jorgensen 1997）包括更广泛的分布和非线性模型，如相关误差的可能性和非线性假设，放弃指数族假设。基于广义Cook距离和Poon & Poon（1999）的共形法曲率，研究了小扰动对NRDM数据集的局部影响。用两个例子来说明我们的结果。
Nonlinear reproductive dispersion models (NRDM, Jorgensen 1997) include a wider range of distributions and nonlinear models such as the possibility of correlated errors and nonlinear hypotheses dropping the exponential family assumption. Based on the generalized Cook distance and the conformal normal curvature of Poon & Poon (1999), local influence of minor perturbations on the data set is investigated for NRDM. Two examples are used to illustrate our results.
