Moments of Order Statistics from Right Truncated Log-Logistic Distribution. [PDF]

The Egyptian Statistical Journal, 1998
            The moments of order statistics from a right truncated log-logistic distribution are given based on hypergeometric function. Some new recurrence relations between the moments of Xr:n are obtained.

Bayesian Analysis of Unit Log-Logistic Distribution Using Non-Informative Priors

Mathematics, 2023
The unit log-logistic distribution is a suitable choice for modeling data enclosed within the unit interval. In this paper, estimating the parameters of the unit-log-logistic distribution is performed through a Bayesian approach with non-informative ...

McDonald log-logistic distribution with an application to breast cancer data [PDF]

Journal of Statistical Theory and Applications (JSTA), 2014
We introduce a five-parameter continuous model, called the McDonald log-logistic distribution, to extend the two-parameter log-logistic distribution.

Quantile Regression with a New Exponentiated Odd Log-Logistic Weibull Distribution

Mathematics, 2023
We define a new quantile regression model based on a reparameterized exponentiated odd log-logistic Weibull distribution, and obtain some of its structural properties.

Discriminating Between the Log-Normal and Log-Logistic Distributions [PDF]

Communications in Statistics - Theory and Methods, 2009
Log-normal and log-logistic distributions are often used to analyze lifetime data. For certain ranges of the parameters, the shape of the probability density functions or the hazard functions can be very similar in nature. It might be very difficult to discriminate between the two distribution functions.

A Prediction Model for Warranty Reserves Using the Log-Logistic Distribution [PDF]

The Egyptian Statistical Journal, 2005
Many products carry warranty that offers protection for the consumer against low quality. This paper considers the problem of assessing the size of reserve needed by the manufacturer to meet future claims. We assume that the failure-time has Log-Logistic

Designing Degradation Experiments Using a Log-Logistic Distribution

Austrian Journal of Statistics, 2016
Assessing the reliability of a product is very important to improve the product’s quality and to get the trust of customers. Degradation experiments are usually used to assess the reliability of highly reliable products, which are not expected to fail ...

A Note on Topp-Leone Odd Log-Logistic Inverse Exponential Distribution

Journal of Statistical Theory and Applications (JSTA), 2020
The inverse exponential distribution is widely used in the field of reliability. In this article, we present a generalization of the inverse exponential distribution in formation of Topp-Leone odd log-logistic inverse exponential distribution. We provide

Topp–Leone odd log-logistic exponential distribution: Its improved estimators and applications

Anais da Academia Brasileira de Ciências, 2021
In this paper, a new three-parameter lifetime model called the Topp–Leone odd log-logistic exponential distribution is proposed. Its density function can be expressed as a linear mixture of exponentiated exponential densities and can be reversed-J shaped,

Truncated log-logistic Family of Distributions

Journal of Biostatistics and Epidemiology, 2020
Background & Aim: There are various data associated with any events in the world which need to be analyzed. In response to this, many researchers attempt to find appropriate methods that could better fit these data using new models. One of these methods is to introduce new distributions which could better describe available data.
