Stochastic Ordering of Exponential Family Distributions and Their Mixtures
Yaming Yu
We investigate stochastic comparisons between exponential family distributions and their mixtures with respect to the usual stochastic order, the hazard rate order, the reversed ha…
Efficient Simulation of a Bivariate Exponential Conditionals Distribution
Yaming Yu
The bivariate distribution with exponential conditionals (BEC) is introduced by Arnold and Strauss [Bivariate distributions with exponential conditionals, J. Amer. Statist. Assoc.…
On an Inequality of Karlin and Rinott Concerning Weighted Sums of i.i.d. Random Variables
Yaming Yu
We present an entropy comparison result concerning weighted sums of independent and identically distributed random variables.
An Inequality for Ratios of Gamma Functions
Yaming Yu
An inequality concerning ratios of gamma functions is proved. This answers a question of Guo and Qi (2003).
Bounds on the Location of the Maximum Stirling Numbers of the Second Kind
Yaming Yu
Let K_n denote the smaller mode of the nth row of Stirling numbers of the second kind S(n, k). Using a probablistic argument, it is shown that for all n>=2, [exp(w(n))]-2<=K_n<=[ex…
A Bit of Information Theory, and the Data Augmentation Algorithm Converges
Yaming Yu
The data augmentation (DA) algorithm is a simple and powerful tool in statistical computing. In this note basic information theory is used to prove a nontrivial convergence theorem…
