A Classification Scheme for Phenomenological Universalities in Growth Problems [PDF]

, 2006
A classification in universality classes of broad categories of phenomenologies, belonging to different disciplines, may be very useful for a crossfertilization among them and for the purpose of pattern recognition.

On Order Restricted Inference in Multi‐Step Stage Life Testing for a General Family of Distributions

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Recently, k$$ k $$‐step stage life testing (SLT) has been proposed by Laumen and Cramer (2021) as a natural extension of progressive censoring with fixed censoring times (PC‐FCT) as well as of simple step‐stress accelerated life testing (SSALT).

A Note on a Characterization of Gompertz-Verhulst Distribution [PDF]

Journal of Statistical Theory and Applications (JSTA), 2014
Characterization of a probability distribution plays an important role in probability and statistics. This paper considers a new characterization of Gompertz-Verhulst distribution. It is hoped that the findings of the paper will be useful for researchers

Quantifying Dual‐Color Photopolymerization in Xolography via Raman Spectroscopy

Journal of Polymer Science, EarlyView.
A dual‐wavelength Raman spectroscopy workflow is presented for the quantitative assessment of dual‐color photoinitiators. Contrast and efficiency parameters are extracted from in situ curing curves and spatial Raman mapping is used to find inhomogeneities in printed objects.

A Novel Gompertz-Type Distribution with Applications to Radiological Dose and Pharmacokinetic Data

Mathematics
This study introduces a novel four-parameter lifetime distribution constructed within the Topp–Leone Power Gompertz framework. Owing to its flexible structure, the proposed model accommodates a wide range of density shapes and hazard-rate patterns ...

An Iterated Local Search Algorithm for Estimating the Parameters of the Gamma/Gompertz Distribution

Modelling and Simulation in Engineering, 2014
Extensive research has been devoted to the estimation of the parameters of frequently used distributions. However, little attention has been paid to estimation of parameters of Gamma/Gompertz distribution, which is often encountered in customer lifetime ...

The Marshall – Olkin Teissier generated model for lifetime data

Журнал Белорусского государственного университета: Математика, информатика, 2022
An accurate mathematical inference depends on the experimental design and the model adopted in the process. Thus, in this study Marshall – Olkin Teissier generated distribution was used to present the distribution of the true nature of lifetime data. The

Colonization and spatiotemporal distribution of bruchid pests in lentil and faba bean fields

Pest Management Science, EarlyView.
This study of 104 fields identifies Bruchus signaticornis in lentils and B. rufimanus in faba beans as the sole grain‐damaging species. Their uniform distribution within fields and the strong effect of regulatory factors on larvae and egg survival emphasize the need for species‐specific, phenology‐based and spatially informed integrated pest management

Classical and Bayesian estimation for Gompertz distribution under the unified hybrid censored sampling with application

AIP Advances, 2023
This study discusses the Gompertz distribution’s statistical inference using unified hybrid censored data. Under various loss functions, the maximum likelihood and Bayesian approaches are explored for estimating the parameters for the Gompertz ...
