Logarithmic complete monotonicity of a matrix-parametrized analogue of the multinomial distribution (2105.01494v3)
Published 3 May 2021 in math.CA, math.FA, and math.PR
Abstract: In the paper, the authors introduce a matrix-parametrized generalization of the multinomial probability mass function that involves a ratio of several multivariate gamma functions. They show the logarithmic complete monotonicity of this generalization and derive new inequalities involving ratios of multivariate gamma functions.
