摘要
针对传统定量数理统计分析受"小样本"、"贫信息"等不确定因素影响较大的局限性,通过原始数据无量纲化处理,采用线性变换及科学有效判定分辨系数的方法,确定了改进的关联系数计算公式,结合模糊数学中的贴近度原理,给出了一种改进的灰色关联度分析理论模型,并应用该方法对导弹研制费用驱动因子进行了实例分析。
Aiming at the fact that uncertain factors such as small sample and poor information have great impacts on traditional quantitative mathematical statistics, using non - dimensional original data, by means of linear transformation and effective determination of discrimination coefficient, computation formula of correlative coefficient is proposed. Integrating the principle of closeness degree in fuzzy system, the improved theoretical model of grey correlative degree analysis is presented. Using this method, the missile developing cost driver factor is analyzed.
