Note on the moment generating function of the multivariate normal distribution

Miskolc Mathematical Notes
We present a streamlined proof of a formula for the derivatives of the moment generating function of the multivariate normal distribution. We formulate it in terms of the summation of the contractions by pairings, which encodes a combinatorial ...

Evidence‐Informed Multidisciplinary Consensus Guidance for the Psychosocial Care of Adolescents With High‐Risk Cancer: Recommendations From the Italian Association of Pediatric Hematology and Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with high‐risk cancer face complex developmental, psychosocial, and ethical challenges that extend beyond disease‐directed treatment. Although international recommendations exist for communication, psychosocial care, pediatric palliative care, survivorship, and shared decision‐making, these have largely evolved within ...

Factorial moment -generating function and the Pascal distribution

, 2004
Given a distribution, the cumulants or factorial moments can be used to obtain the skewness and kurtosis which in turn are used to determine the normal approximation of the given distribution.

Nonparametric Recursive Kernel Type Eestimators for the Moment Generating Function Under Censored Data

, 2023
International audienceWe are mainly concerned with kernel-type estimators for the moment-generating function in the present paper. More precisely, we establish the central limit theorem with the characterization of the bias and the variance for the ...

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...

A New Family of Discrete Distributions with Mathematical Properties, Characterizations, Bayesian and Non-Bayesian Estimation Methods

Mathematics, 2020
In this work, we propose and study a new family of discrete distributions. Many useful mathematical properties, such as ordinary moments, moment generating function, cumulant generating function, probability generating function, central moment, and ...

Some Properties of the Moment-Generating Function [PDF]

, 1969
This paper deals with properties of the moment-generating function. Although there are many properties of the moment-generating function, this paper will concentrate on some of the most ofter used properties of that function.

SOME DEFICIENCIES IN USING MOMENT GENERATING FUNCTIONS

, 2004
Two deficiencies in using moment-generating functions are given and illustrated with examples. Many distributions do not have moment generating functions, but every distribution has a unique characteristic function. The use of characteristic functions is

New Distribution with Statistical Properties and Classical Estimation Method

Ibn Al-Haitham Journal for Pure and Applied Sciences
In the present study, we propose a new model, identified as the Shanker Rayleigh distribution, which is derived by combining the survival functions of the classical Rayleigh and Shanker distributions, both of which have a scale parameter only.
