Limiting distributions of the likelihood ratio test statistics for independence of normal random vectors
Mingyue Hu, Yongcheng Qi
Consider the likelihood ratio test (LRT) statistics for the independence of sub-vectors from a -variate normal random vector. We are devoted to deriving the limiting distributio…
Pearson's goodness-of-fit tests for sparse distributions
Shuhua Chang, Deli Li, Yongcheng Qi
Pearson's chi-squared test is widely used to test the goodness of fit between categorical data and a given discrete distribution function. When the number of sets of the categorica…
Spectral Radii of Large Non-Hermitian Random Matrices
Tiefeng Jiang, Yongcheng Qi
By using the independence structure of points following a determinantal point process, we study the radii of the spherical ensemble, the truncation of the circular unitary ensemble…
Test for a Mean Vector with Fixed or Divergent Dimension
Liang Peng, Yongcheng Qi, Fang Wang
It has been a long history in testing whether a mean vector with a fixed dimension has a specified value. Some well-known tests include the Hotelling -test and the empirical l…
A Refinement of the Kolmogorov-Marcinkiewicz-Zygmund Strong Law of Large Numbers
Deli Li, Yongcheng Qi, Andrew Rosalsky
For the partial sums formed from a sequence of i.i.d. random variables having a finite absolute p'th moment for some p in (0,2), we extend the recent and striking discovery of Hech…
