**摘要**:变点检测问题是确定是否发生了变化。针对独立分布中的变点问题,提出了两种基于经验似然和似然比的非参数方法。
ABSTRACT The change-point detection problem is determining whether a change has taken place. Two non parametric methods based on empirical likelihood and the likelihood ratio are proposed for detecting a change-point problem in distributions for independent observations. Numerical studies are carried out to evaluate the performance of the proposed methods. The simulation results demonstrate that the proposed methods are robust, that is, they perform well regardless of whether the observations are from the same distribution family.
