Abstract
A method is presented for determining the breakpoint of a line which suddenly changes slope at some unknown point. A statistical test is given for testing whether the broken line is a significantly better fit to the data than a single straight line. An approximate confidence interval can be obtained for the position of the breakpoint.
摘要
本文提出了一种确定在某个未知点斜率突然变化的直线断点的方法。给出了一种统计检验，用于检验折线对数据的拟合是否明显优于单一的直线。可以获得断点位置的近似置信区间。
