Abstract: A new non-linear discriminant method is proposed. It can be applied in failure diagnosis and quality control. The algorithm is presented, and basic properties are investigated. The method is simple. It can be easily programmed and widely used. The effectiveness and engineering practicability of the method is shown in diagnosing ball bearing skidding defect.

Key words: discriminant function set, failure diagnosing, stepwise discriminant analysis
