论文摘要
在高频框架内,我们提出了一种非参数方法,以估计与时间变化的布朗尼运动相关的一系列Copulas家族。我们表明我们的估计器是一致且渐近混合的高斯。此外,我们通过Monte Carlo测试了其有限样本的精度。
Within a high-frequency framework, we propose a non-parametric approach to estimate a family of copulas associated to a time-changed Brownian motion. We show that our estimator is consistent and asymptotically mixed-Gaussian. Furthermore, we test its finite-sample accuracy via Monte Carlo.
