Inverse Unit Teissier Distribution: Theory and Practical Examples

open access: yesAxioms, 2023
In this paper, we emphasize a new one-parameter distribution with support as [1,+∞). It is constructed from the inverse method applied to an understudied one-parameter unit distribution, the unit Teissier distribution.

The evolutionarily stable distribution of fitness effects [PDF]

open access: yesGenetics, 2014
The distribution of fitness effects of new mutations (the DFE) is a key parameter in determining the course of evolution. This fact has motivated extensive efforts to measure the DFE or to predict it from first principles. However, just as the DFE determines the course of evolution, the evolutionary process itself constrains the DFE. Here, we analyze a

Generating Virtual Even-Aged Silver Fir Stand Structure Based on the Measured Sample Plots

open access: yesSouth-East European Forestry, 2016
Background and Purpose: The aim of this article is to create a virtual forest stand based on the field measurement of spatially separated sample plots and to examine its credibility based on the deviation of the basic characteristics of the virtual stand

New Distribution for Fitting Discrete Data: The Poisson-Gold Distribution and Its Statistical Properties

open access: yesAustrian Journal of Statistics, 2021
Motivated mainly by lifetime issues, a new lifetime distribution coined ``Discrete Poisson-Gold distribution'' is introduced in this paper. Different structural properties of the new distribution are derived including moment generating function and the ...

Modelling travel time distribution and its influence over stochastic vehicle scheduling

open access: yesTransport, 2019
Due to the paucity of well-established modelling approaches or well-accepted travel time distributions, the existing travel time models are often assumed to follow certain popular distributions, such as normal or lognormal, which may lead to results ...

A Statistical Method for Estimating Activity Uncertainty Parameters to Improve Project Forecasting

open access: yesEntropy, 2019
Just like any physical system, projects have entropy that must be managed by spending energy. The entropy is the project’s tendency to move to a state of disorder (schedule delays, cost overruns), and the energy process is an inherent part of any ...

Effects of different seasonal fitting methods on the spatial distribution characteristics of common mode errors

open access: yesFrontiers in Earth Science, 2023
This study investigated the effects of various seasonal fitting techniques on the spatial distribution of the common mode errors taking the coordinate time series of the continuous GPS reference stations of the Crustal Movement Observation Network of ...

Modelling of non‐Markovian queuing systems

open access: yesTechnological and Economic Development of Economy, 2006
The purpose of this paper is to suggest a method and software for evaluating queuing approximations. A numerical queuing model with priorities is used to explore the behaviour of exponential phase‐type approximation of service‐time distribution.
