利用SAS软件对271株肠杆菌进行数值分类初探

MAKING NUMERICAL CLASSIFICATION AND IDENTIFICATION TO 271 ENTEROBACTERIACEAES BY SAS SOFTWARE

利用ＳＡＳ软件对肠杆菌科中的９０株标准菌进行系统聚类，去掉独立菌再结合判别分析的应用条件，建立了肠杆菌关于７类属（或种）的筛选变量与不筛选变量的两种判别函数。对１８１株临床菌用两种判别函数进行判别，判得结果的一致率为８７．５７％。对标准菌进行回代，与原分类情况作比较，结果是：不筛选变量时符合率为８９．４１％，筛选变量时符合率为９７.６５％。

SAS software is the one of the best software in the world. This article makes hierarchical cluster to 90 standardenterobacteriaceaes by the software. We have obtained discriminant functions of screening variable and no screening variablewhen without simple enterobacteriaceae and in the light Of the condition of discriminant analysis. Consistent rate is 87.57%when discriminanting 181 clinical enterobacteriaceaes; coincident rates of no screening variable and no screening variable are97.65% and 89.41% respectively.
