摘要
利用曲率方法研究了Logistic模型的局部影响,推导出了漂移扰动、加权扰动、自变量扰动及因变量扰动下的曲率计算公式,最后给出了实例分析,证实了结论的有效性.
This paper systematically discusses the local influence of Logistic statistical model by use of the curva- ture method. The counting formulas of curvature for mean shift perturbation, case weights perturbation, arguments perturbation and the dependent varible perturbation are derived. At last, a case study are given to illustrate our re- suits.
