基于动态线性回归的一阶导数分段法在螺纹检测数据处理中的应用

摘要

提出了一种基于动态线性回归的一阶导数分段方法，并成功应用于螺纹检测数据处理中． 实践证明这是一种有效的对测量数据进行分类的方法．%A first differential grouping method based on dynamic linear regression is described. The method is successfully used in data processing of the thread testing. It has been verified that this method is efficient in grouping testing data.
