摘要
运用基于WilksΛ准则的逐步判别分析来挑选对诊断轴承滑动探伤起显著作用的特征,在正态母体假设下,对Bayes判别模型导出用于诊断轴承滑动擦伤的线性判别函数.方法简单可靠,可用于轴承生产的质量管理.
Those features having more influence on the disgnosi of boring skidding defectare selected by using stepwise discriminant analysis on the basis of the wilks Λ criterion.The linear discriminant functions are derived from myes discriminant model on condition that sample is o f normal distribution. The method in the paper is simple, rehable and can be apPlied to quality control of bearing production.
