多元波动率非参数估计的傅里叶变换方法

A Fourier transform method for nonparametric estimation of multivariate volatility

Paul Malliavin, Maria Elvira Mancino

摘要:

基于傅里叶分析,提出了一种计算连续半鞅瞬时波动率的非参数方法。通过建立价格过程的傅里叶变换与协波动过程的傅里叶变换之间的联系,将协波动重构为时间的随机函数。给出了资产价格过程的离散非均匀间隔和异步采样观测值的非参数估计。随机估计的渐近性质进行了研究:即,一致的时间和收敛规律的混合高斯分布的概率的一致性。

英文摘要:

We provide a nonparametric method for the computation of instantaneous multivariate volatility for continuous semi-martingales, which is based on Fourier analysis. The co-volatility is reconstructed as a stochastic function of time by establishing a connection between the Fourier transform of the prices process and the Fourier transform of the co-volatility process. A nonparametric estimator is derived given a discrete unevenly spaced and asynchronously sampled observations of the asset price processes. The asymptotic properties of the random estimator are studied: namely, consistency in probability uniformly in time and convergence in law to a mixture of Gaussian distributions.
