摘要翻译：
设$(X_i)_{i=1,...,n}$是一个可能的非平稳序列，使得$\mathscr{L}(X_i)=P_n$if$i\leq n\theta$和$\mathscr{L}(X_i)=q_n$if$i>n\theta$,其中$0<\theta<1$是待估计的变化点的位置。我们在经验测度的基础上构造了一类估计量，并在通过函数族$\mathcal{F}$定义的测度空间上构造了半范数。证明了该估计量的相合性，并给出了一般条件下的收敛速度。特别地，对于包括长程相关序列甚至非平稳序列在内的许多过程，都可以达到$1/N$速率。该方法对已有的参数和非参数变点估计结果进行了统一、推广和改进，适用于独立序列、短程相关序列和长程相关序列。

英文摘要：
  Let $(X_i)_{i=1,...,n}$ be a possibly nonstationary sequence such that $\mathscr{L}(X_i)=P_n$ if $i\leq n\theta$ and $\mathscr{L}(X_i)=Q_n$ if $i>n\theta$, where $0<\theta <1$ is the location of the change-point to be estimated. We construct a class of estimators based on the empirical measures and a seminorm on the space of measures defined through a family of functions $\mathcal{F}$. We prove the consistency of the estimator and give rates of convergence under very general conditions. In particular, the $1/n$ rate is achieved for a wide class of processes including long-range dependent sequences and even nonstationary ones. The approach unifies, generalizes and improves on the existing results for both parametric and nonparametric change-point estimation, applied to independent, short-range dependent and as well long-range dependent sequences.
