Complete monotonicity of a difference constituted by four derivatives of a function involving trigamma function [PDF]

Mathematical Inequalities & Applications, 2020
In the paper, by virtue of convolution theorem for the Laplace transforms, Bernstein's theorem for completely monotonic functions, and other techniques, the author finds necessary and sufficient conditions for a difference constituted by four derivatives of a function involving trigamma function to be completely monotonic.

Euler Sums and Integral Connections

Mathematics, 2019
In this paper, we present some Euler-like sums involving partial sums of the harmonic and odd harmonic series. First, we give a brief historical account of Euler’s work on the subject followed by notations used in the body of the paper.

Monotonic functions related to the $q$-gamma and q-trigamma functions with applications [PDF]

Journal of Classical Analysis, 2017
Summary: In this paper, our aim is to investigate necessary and sufficient conditions for the complete monotonicity properties of some functions related to the \(q\)-gamma and \(q\)-trigamma functions. As application of this results, some new inequalities are derived.

Accurate agreement estimation in crowdsourced relevance assessments via statistical models based on the beta distribution

Statistica Neerlandica, Volume 80, Issue 4, November 2026.
Abstract Data crowdsourcing is often used to collect relevance assessments in information retrieval tasks. However, estimating the agreement among crowdworkers is nontrivial, since data is sparse and often collected on a variety of rating scales.

Closed-form estimators for the inverse Nakagami distribution

Anais da Academia Brasileira de Ciências
The inverse Nakagami distribution due to Louzada et al. (2018) does not have closed-form maximum likelihood estimators. Closed-form estimators by adapting the method of moments are proposed in this note.
