摘要
给出了多元判别分析的数学原理和方法,通过对正规方程组解的简化处理,在不影响分类判别决策的前提下获得了判别函数.用实例说明了模型在生态环境中样品分类判别研究上的应用.
The mathematical principle and method is given.Through simplification of key normal equation set,the decision function is obtained and the effect of decision is not affected.The application of model is exemplified in classified decision of samples in ecological environment.
