On the measure concentration of infinitely divisible distributions

Jing Zhang, Ze-Chun Hu, Wei Sun

Let $I$ be the set of all infinitely divisible random variables\ with finite second moments, $I_{0} = {X \in I : Var (X) > 0}$ , $P_{\cal I}=\inf_{X\in{\cal I}}P\{…

Some New Results on Gaussian Product Inequalities

Qian-Qian Zhou, Han Zhao, Ze-Chun Hu +1

The long-standing Gaussian product inequality (GPI) conjecture states that, for any centered $R^{n}$ -valued Gaussian random vector $(X_{1}, \dots, X_{n})$ and any positive reals…

The infimum values of the probability functions for some infinitely divisible distributions motivated by Chvátal's theorem

Ze-Chun Hu, Peng Lu, Qian-Qian Zhou +1

Let $B (n, p)$ denote a binomial random variable with parameters $n$ and $p$ . Chvátal's theorem says that for any fixed $n \geq 2$ , as $m$ ranges over ${0, \dots, n}$ , the probabilit…

Variation comparison between the $F$ -distribution and the normal distribution

Ping Sun, Ze-Chun Hu, Wei Sun

Let $X_{d_{1}, d_{2}}$ be an $F$ -random variable with numerator and denominator degrees of freedom $d_{1}$ and $d_{2}$ , respectively. We investigate the inequality: $P\{|X_{d_1,d_2}-E[X_{d_…

Variation comparison between infinitely divisible distributions and the normal distribution

Ping Sun, Ze-Chun Hu, Wei Sun

Let $X$ be a random variable with finite second moment. We investigate the inequality: $P {∣ X - E [X] ∣ \leq Var (X)} \geq P {∣ Z ∣ \leq 1}$ , where $Z$ is a standard normal rando…
