General formulas for the central and non-central moments of the multinomial distribution

open access: yes, 2021
We present the first general formulas for the central and non-central moments of the multinomial distribution, using a combinatorial argument and the factorial moments previously obtained in Mosimann (1962).

Proof of conjectures on the standard deviation, skewness and kurtosis of the shifted Gompertz distribution [PDF]

open access: yes, 2021
Three conjectures on the standard deviation, skewness and kurtosis of the shifted Gompertz distribution, as the shape parameter increases to +∞, are proved. In this regard, the exponential integral function and polygamma functions are used in the proofs.

Applied and Computational Statistics [PDF]

open access: yes, 2020
Research without statistics is like water in the sand; the latter is necessary to reap the benefits of the former. This collection of articles is designed to bring together different approaches to applied statistics.

Shape theory via polar decomposition [PDF]

open access: yes, 2010
This work proposes a new model in the context of statistical theory of shape, based on the polar decomposition. The non isotropic noncentral elliptical shape distributions via polar decomposition is derived in the context of zonal polynomials, avoiding ...

Double Weighted Distribution & Double Weighted Exponential Distribution [PDF]

open access: yes, 2013
Since the widely using of the weighted distribution in many fields of real life such various areas including medicine, ecology, reliability, and so on, then we try to shed light and record our contribution in this field thru the research.
