英文摘要:
In this paper, we give a general time-varying parameter model, where the multidimensional parameter possibly includes jumps. The quantity of interest is defined as the integrated value over time of the parameter process $\\Theta = T^{-1} \\int_0^T \\theta_t^* dt$. We provide a local parametric estimator (LPE) of $\\Theta$ and conditions under which we can show the central limit theorem. Roughly speaking those conditions correspond to some uniform limit theory in the parametric version of the problem. The framework is restricted to the specific convergence rate $n^{1/2}$. Several examples of LPE are studied: estimation of volatility, powers of volatility, volatility when incorporating trading information and time-varying MA(1).

中文摘要:
本文给出了一个一般的时变参数模型,其中多维参数可能包含跳跃。兴趣量定义为参数process$\\Theta=T^{-1}\\int_0^T\\Theta_T^*dt$随时间的积分值。我们给出了$\\Theta$的局部参数估计(LPE)和证明中心极限定理的条件。粗略地说,这些条件对应于问题的参数化版本中的统一极限理论。该框架仅限于特定的收敛速度$n^{1/2}$。研究了LPE的几个例子:波动率的估计、波动率的幂、合并交易信息时的波动率和时变MA(1)。
