多年来多指标分析,诸如:多元回归,逐步回归,聚类分析,判别分析,主成份分析等必须经过复杂计算过程的多因素统计方法,它要求相当复杂的计算工具与数学和统计学基础,给基层应用带来一定困难。然而分析研究多指标又系专业工作之必须。模糊数学综合评判法对于多指标综合评价,计算方法简便,原理直观容易理解,有较大的实用性。现以某地独生和非独生儿童体质和视力等指标为例(表1、表2、表3),运用模糊数学综合评价法,进行综合评价与分析。
Over the years, multi-indicator analysis, such as: multiple regression, stepwise regression, cluster analysis, discriminant analysis, principal component analysis, etc., has had to go through a multi-factor statistical method for complex calculation processes. It requires rather complex calculation tools and mathematical and statistical foundations. Bring some difficulties to basic applications. However, the analysis and research of multiple indicators are necessary for professional work. The fuzzy mathematics comprehensive evaluation method is simple and easy to understand for the multi-index comprehensive evaluation, the principle is intuitive and easy to understand, and has greater practicality. Now take the physical fitness and visual acuity indexes of the only child and non-exclusive child as an example (Table 1, Table 2, Table 3), and use the fuzzy mathematics comprehensive evaluation method to conduct comprehensive evaluation and analysis.
