摘要
马氏距离是多元统计中常用的一种判别方法。以实例分析了马氏距离方法在路面使用性能评价中的应用,阐述马氏距离法的基本思路和操作步骤,论证了马氏距离法的科学性、合理性和实用性。与我国常用的综合评价方法相比,马氏距离是具有物理意义的指标,可以用于路面综合性能的评价。
Mahalannobis distance method is a usual way of multivariate statistical analysis. In this paper, an example was used to analysis the application of Mahalannobis distance method in the road service performance evaluation. And the paper introduces the basic thinking and operational procedures , at the same time it verified the scientific, reasonable and practical of the method. Contrast to the usual overall evaluation methods, Mahalannobis distance method has physical meaning indexes, it can be used in the road overall performance evaluation.
