On the exponentiated Weibull distribution [PDF]

open access: yesAIP Conference Proceedings, 2019
A new generated family of continuous distributions based on exponentiated Weibull has been introduced. Then exponentiated Weibull - exponentiated Weibull distribution is proposed as a special case of this family. The cumulative distribution, probability density, expansion of probability density, reliability and hazard rate functions are presented ...

Solutions for better fitting Sigmoid-shaped functions to binary data [PDF]

open access: yesComputational Ecology and Software, 2020
Sigmoid-shaped curves are often used to estimate the probability of individuals surviving or becoming fecund (response: y) given some characteristic like age or size (predictor: x).

q-exponential, Weibull, and q-Weibull distributions: an empirical analysis [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2003
In a comparative study, the q-exponential and Weibull distributions are employed to investigate frequency distributions of basketball baskets, cyclone victims, brand-name drugs by retail sales, and highway length. In order to analyze the intermediate cases, a distribution, the q-Weibull one, which interpolates the q-exponential and Weibull ones, is ...

Evolution and Kantian morality: a correction and addendum [PDF]

open access: yes, 2023
Theorem 1 in Alger and Weibull (Games and Economic Behavior, 2016) consists of two statements. The first establishes that Homo moralis with the right degree of morality is evolutionarily stable. The second statement is a claim about sufficient conditions
