Application of the Exponentiated Log-Logistic Weibull Distribution to Censored Data

open access: yesJournal of Nigerian Society of Physical Sciences, 2019
In a recent paper, a new model called the Exponentiated Log-Logistic Weibull (ELLoGW) distribution with applications to reliability, survival analysis and income data was proposed.

Bayesian logistic regression for presence-only data [PDF]

open access: yes, 2015
Presence-only data are referred to situations in which a censoring mechanism acts on a binary response which can be partially observed only with respect to one outcome, usually denoting the \textit{presence} of an attribute of interest. A typical example

Likelihood estimators for multivariate extremes [PDF]

open access: yes, 2015
The main approach to inference for multivariate extremes consists in approximating the joint upper tail of the observations by a parametric family arising in the limit for extreme events. The latter may be expressed in terms of componentwise maxima, high

Grid multi-category response logistic models. [PDF]

open access: yes, 2015
BackgroundMulti-category response models are very important complements to binary logistic models in medical decision-making. Decomposing model construction by aggregating computation developed at different sites is necessary when data cannot be moved ...

Statistical Inference of the Lifetime Performance Index with the Log-Logistic Distribution Based on Progressive First-Failure-Censored Data

open access: yesSymmetry, 2020
Estimating the accurate evaluation of product lifetime performance has always been a hot topic in manufacturing industry. This paper, based on the lifetime performance index, focuses on its evaluation when a lower specification limit is given.

Parameter Estimation for the Log-Logistic Distribution Based on Order Statistics

open access: yesRevstat Statistical Journal, 2018
In this paper, we discuss the moments and product moments of the order statistics in a sample of size n drawn from the log-logistic distribution. We provide more compact forms for the mean, variance and covariance of order statistics.

Numerical Study of the Oscillatory Convergence to the Attractor at the Edge of Chaos

open access: yes, 2005
This paper compares three different types of ``onset of chaos'' in the logistic and generalized logistic map: the Feigenbaum attractor at the end of the period doubling bifurcations; the tangent bifurcation at the border of the period three window; the ...

Alkaline Water and Longevity: A Murine Study [PDF]

open access: yes, 2016
The biological effect of alkaline water consumption is object of controversy. The present paper presents a 3-year survival study on a population of 150 mice, and the data were analyzed with accelerated failure time (AFT) model.

DISCRIMINATING BETWEEN LOG-LOGISTIC AND RAYLEIGH DISTRIBUTIONS

open access: yesPakistan Journal of Statistics and Operation Research, 2014
Test statistics based on likelihood function, order statistics, population quantiles are suggested to discriminate between log-logistic distribution and Rayleigh distribution. Because of non tractability of their exact sampling distributions, the percentiles of the proposed test statistics are tabulated with the help of simulated sampling distributions
