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…

Limiting Distributions of Spectral Radii for Product of Matrices from the Spherical Ensemble

Shuhua Chang, Deli Li, Yongcheng Qi

Consider the product of $m$ independent $n \times n$ random matrices from the spherical ensemble for $m \geq 1$ . The spectral radius is defined as the maximum absolute value of the $n…

On Tests for Complete Independence of Normal Random Vectors

Shuhua Chang, Yongcheng Qi

Consider a random sample of $n$ independently and identically distributed $p$ -dimensional normal random vectors. A test statistic for complete independence of high-dimensional norm…

A Simple Point Estimator of the Power of Moments

Shuhua Chang, Deli Li, Yongcheng Qi +1

Let $X$ be an observable random variable with unknown distribution function $F (x) = P (X \leq x), - \infty < x < \infty$ , and let \[\ θ= \sup\left \{ r \geq 0:~ \mathbb{E}|…

Empirical Distribution of Scaled Eigenvalues for Product of Matrices from the Spherical Ensemble

Shuhua Chang, Yongcheng Qi

Consider the product of $m$ independent $n \times n$ random matrices from the spherical ensemble for $m \geq 1$ . The empirical distribution based on the $n$ eigenvalues of the product…
