Some Characterizations of the Log-Logistic Distribution

Stochastics and Quality Control, 2018
Abstract The log-logistic distribution is a right skewed distribution of a random variable whose logarithm has the logistic distribution. In this paper, characterizations based on truncated moments, functions of order statistics and record values are obtained. Also, limiting distributions for the extreme order statistics are studied.

Transmuted Log-Logistic Distribution

Journal of Statistics Applications & Probability, 2013
A generalization of the log-logistic distribution so-called the transmuted log-logistic distribution is proposed and studied. Various structural properties including explicit expressions for the moments, quantiles, mean deviations of the new distribution are derived. The estimation of the model parameters is performed by maximum likelihood method.

Unit Log-Logistic Distribution and Unit Log-Logistic Regression Model

Journal of the Indian Society for Probability and Statistics, 2021
In this paper, the unit log-logistic distribution was proposed. This distribution is obtained through by transformation of a random variable with log-logistic distribution. The unit log-logistic has closed forms for the cumulative distribution function and quantile function.

Reliability Test Plans for Exponentiated Log-Logistic Distribution

Economic Quality Control, 2006
Summary: A generalization of the log-logistic distribution, called exponentiated log-logistic distribution [in lines of the exponentiated Weibull distribution suggested by \textit{G. S. Mudholkar} et al., Technometrics 37, No. 4, 436--445 (1995)] is considered.

Estimator based on percentiles for log-logistic distribution

2012 International Conference on Statistics in Science, Business and Engineering (ICSSBE), 2012
In this study, we consider the estimator based on percentiles for log-logistic distribution similar to the study of [6] and we also graph breakdown plots of the estimators that are considered below to have an opinion about robustness properties. The estimator based on percentiles is explicit functions of sample percentiles, thus, easy to compute and do

Estimating the failure rate of the log-logistic distribution by smooth adaptive and bias-correction methods [PDF]

Computers and Industrial Engineering, 2021
The Log-logistic distribution has successfully earned attention in practical applications due to its good statistical properties. Because the traditional maximum likelihood estimators of the Log-logistic distribution parameters do not have an explicit ...

Control Charts for the Log-Logistic Distribution

Economic Quality Control, 2006
Summary: This paper deals with the log-logistic distribution as a life time model. Control charts and the corresponding control limits are developed analogous to Shewhart-charts for the process mean and process range. The proposed control limits are compared with those of Shewhart in detecting out of control signals for various sample sizes.

Objective Bayesian Analysis for Log-logistic Distribution

Communications in Statistics - Simulation and Computation, 2015
In this article, Bayesian approach is applied to estimate the parameters of Log-logistic distribution under reference prior and Jeffreys’ prior. The reference prior is derived and it is found that the reference prior is also a second-order matching priors as for the case of any parameter of interest.
