Determination of the most appropriate method for extrapolating overall survival data from a placebo-controlled clinical trial of lenvatinib for progressive, radioiodine-refractory differentiated thyroid cancer [PDF]

open access: yes, 2016
Background: Cost-effectiveness models for the treatment of long-term conditions often require information on survival beyond the period of available data.

THE TRANSMUTED GAMMA-GOMPERTZ DISTRIBUTION

open access: yesInternational Journal of Research -GRANTHAALAYAH, 2020
This article introduces a four-parameter probability model which represents a gener- alization of the the Gamma-Gompertz distribution using the quadratic rank trans- mutation map. The proposed model is named the Transmuted Gamma-Gompertz distribution. We provide explicit expressions for its statistical properties, moment generating function, quantile ...

ON THE MOMENTS OF THE 3-PARAMETER GOMPERTZ DISTRIBUTION

open access: yesBarekeng
Gompertz distribution is a classical probability distribution extensively used in actuarial science, reliability, and survival analysis. Gompertz distribution also plays a role in various fields, such as biology, economics, and marketing analysis.

New Modified Gompertz Probability Distribution With Flexible Hazard Functions

open access: yesJournal of Probability and Statistics
This paper introduces a new probability model called the modified Gompertz distribution from the base Gompertz distribution by combining its hazard function with first and second degree polynomial (linear and quadratic) functions.

Theory and Applications of the Unit Gamma/Gompertz Distribution

open access: yesMathematics, 2021
Unit distributions are commonly used in probability and statistics to describe useful quantities with values between 0 and 1, such as proportions, probabilities, and percentages. Some unit distributions are defined in a natural analytical manner, and the

Evidence for the Gompertz Curve in the Income Distribution of Brazil 1978-2005

open access: yes, 2008
This work presents an empirical study of the evolution of the personal income distribution in Brazil. Yearly samples available from 1978 to 2005 were studied and evidence was found that the complementary cumulative distribution of personal income for 99%

Simulations of a mortality plateau in the sexual Penna model for biological ageing [PDF]

open access: yes, 2005
The Penna model is a strategy to simulate the genetic dynamics of age-structured populations, in which the individuals genomes are represented by bit-strings.

Polylimonene Improves the In Vivo Wound Healing Performance of Sodium Alginate‐Based Hydrogels

open access: yesJournal of Applied Polymer Science, EarlyView.
An oligomer derived from orange peel essential oil incorporated into an alginate hydrogel was shown to be biocompatible and to exhibit a high capacity for in vivo incisional wound healing, as confirmed by experimental assays and mathematical models fitted to the data describing wound area reduction as a function of the dressing‐tissue contact time ...

The Modified Beta Gompertz Distribution: Theory and Applications

open access: yesMathematics, 2018
In this paper, we introduce a new continuous probability distribution with five parameters called the modified beta Gompertz distribution. It is derived from the modified beta generator proposed by Nadarajah, Teimouri and Shih (2014) and the Gompertz ...

Compelling Evidence of Oscillatory Behaviour of Hadronic Multiplicities in the Shifted Gompertz Distribution

open access: yesAdvances in High Energy Physics, 2020
Study of charged particle multiplicity distribution in high-energy interactions of particles helps in revealing the dynamics of particle production and the underlying statistical patterns, by which these distributions follow.
