With the rapid development of Chinese economic, enterprise cost control and management of enterprise face enormous challenges. Traditional cost control and management are almost dominated by after-cos...
On the Estimation of Integrated Covariance Matrices of High Dimensional Diffusion Processes
High dimension high frequency integrated covariance matrix
2010/10/20
We consider the estimation of integrated covariance matrices of high dimensional diffusion processes by using high frequency data. We start by studying the most commonly used estimator, the realized ...
