Least informative distributions in Maximum q-log-likelihood estimation

open access: yes, 2017
We use the Maximum $q$-log-likelihood estimation for Least informative distributions (LID) in order to estimate the parameters in probability density functions (PDFs) efficiently and robustly when data include outlier(s). LIDs are derived by using convex

Mechanical property variation mechanisms of granite subjected to real‐time high temperatures and subsequent cooling treatment

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigates the coupled thermo‐mechanical behavior of granite during heating and cooling through a combination of laboratory tests and finite element analysis. The thermal conductivity, mineral composition, mass loss rate, micro‐crack observation, and thermal fracture characteristics of granite under various temperature conditions are ...

The Weibull-Gamma Distribution: Properties and Applications

open access: yesEntropy, 2019
A new member of the Weibull-generated (Weibull-G) family of distributions—namely the Weibull-gamma distribution—is proposed. This four-parameter distribution can provide great flexibility in modeling different data distribution shapes.

Evaluation of three methods for estimating the Weibull distribution parameters of Chinese pine (Pinus tabulaeformis )

open access: yesJournal of Forest Science, 2008
Weibull distribution was used to fit tree diameter data collected from 86 sample plots located in Chinese pine stand in Beijing. To estimate the Weibull distribution parameters, three methods [namely maximum likelihood estimation method (MLE), method of ...

Categorical data analysis using a skewed Weibull regression model

open access: yes, 2017
In this paper, we present a Weibull link (skewed) model for categorical response data arising from binomial as well as multinomial model. We show that, for such types of categorical data, the most commonly used models (logit, probit and complementary log-

Bayesian and non-Bayesian estimation for Weibull parameters based on generalized type-ii progressive hybrid censoring scheme

open access: yes, 2016
Bayesian and non-Bayesian estimators are obtained for the unknown parameters of Weibull distribution based on the generalized Type-II progressive hybrid censoring scheme and different special cases are obtained.
