CLT for random quadratic forms based on sample means and sample covariance matrices

Wenzhi Yang, Yiming Liu, Guangming Pan +1

In this paper, we use the dimensional reduction technique to study the central limit theory (CLT) random quadratic forms based on sample means and sample covariance matrices. Speci…

Testing Kronecker Product Covariance Matrices for High-dimensional Matrix-Variate Data

Long Yu, Jiahui Xie, Wang Zhou

Kronecker product covariance structure provides an efficient way to modeling the inter-correlations of matrix-variate data. In this paper, we propose testing statistics for Kroneck…

Factor Modelling for Clustering High-dimensional Time Series

Bo Zhang, Guangming Pan, Qiwei Yao +1

We propose a new unsupervised learning method for clustering a large number of time series based on a latent factor structure. Each cluster is characterized by its own cluster-spec…

Statistical inference in massive datasets by empirical likelihood

Xuejun Ma, Shaochen Wang, Wang Zhou

In this paper, we propose a new statistical inference method for massive data sets, which is very simple and efficient by combining divide-and-conquer method and empirical likeliho…

The rate of convergence of harmonic explorer to SLE4

Shi-Yi Lan, Jin Ma, Wang Zhou

Using the estimate of the difference between the discrete harmonic function and its corresponding continuous version we derive a rate of convergence of the Loewner driving function…
