面板数据中的鲁棒变点检测

Robust change-point detection in panel data

Alexander Dürre, Roland Fried

摘要:

在面板数据中,我们观察到一个时间段T内的个体数量通常很高。即使T很大,人们也经常假设模型随时间的稳定性。我们提出了一个非参数的和强大的测试,在位置的变化,并推导出其渐近分布下的短程依赖和N,T趋于无穷大。一些模拟结果表明,它的实用性下重尾分布。

英文摘要:

In panel data we observe a usually high number N of individuals over a time period T. Even if T is large one often assumes stability of the model over time. We propose a nonparametric and robust test for a change in location and derive its asymptotic distribution under short range dependence and for N, T tending to infinity. Some simulations show its usefulness under heavy tailed distributions.
