Analysis for Xgamma Parameters of Life under Type-II Adaptive Progressively Hybrid Censoring with Applications in Engineering and Chemistry [PDF]
, 2021 Censoring mechanisms are widely used in various life tests, such as medicine, engineering, biology, etc., as they save (overall) test time and cost. In this context, we consider the problem of estimating the unknown xgamma parameter and some survival ...

Estimation of the Inverse Weibull Distribution Parameters under Type-I Hybrid Censoring
Austrian Journal of Statistics, 2021 The hybrid censoring is a mixture of type-I and type-II censoring schemes. This paper presents the statistical inferences of the inverse Weibull distribution parameters when the data are type-I hybrid censored.

Lindley’s approximation in estimating two-parameters inverted weighted exponential distribution [PDF]
The Inverted Weighted Exponential (IWE) distribution can be used to describe and model real-life phenomena with unimodal or decreasing failure rates. The main aim of this study is to use the Bayesian approach to estimate the two parameters of ...

Bayes Estimation of the Scale Parameter of the Logistic Distribution Based on Progressive First-Failure Censored Scheme [PDF]
, 2017 In this paper we develop approximate Bayes estimators of the scale parameter of the logistic distribution, based on a new life test plan called a progressive first-failure censored plan introduced by [22].

Bayesian Estimations using MCMC Approach under Exponentiated Rayleigh Distribution Based on Unified Hybrid Censored Scheme [PDF]
, 2017 This paper aims to estimate the unknown parameters, survival and hazard functions for exponentiated Rayleigh distribution based on unified hybrid censored data. The maximum likelihood and Bayes methods are used for estimating the two unknown parameters as

Limnology and Oceanography: Methods, EarlyView.Abstract Assigning taxonomic identity and thus assessing taxonomic diversity in gelatinous zooplankton is challenging due to their fragility and difficult preservation. Formalin fixation compromises DNA integrity, while flash‐freezing, ethanol, and acetone preservation affect morphological features. In this study, we developed a methodological protocol

Nordic Journal of Botany, EarlyView.Guapira Aubl. (Nyctaginaceae, Pisonieae) comprises dioecious shrubs and trees widely distributed in the Neotropics and occupying diverse habitats. In the Brazilian Cerrado, the genus occurs in several phytophysiognomies, including Campos Rupestres, a montane rock ecosystem with high levels of endemism but still marked by significant gaps in botanical ...

Quality and Reliability Engineering International, EarlyView.ABSTRACT We propose a practical procedure to quantify the time varying influence of parameters on hazard functions for power series compounded lifetime models. The procedure combines likelihood based fitting with a two stage sensitivity analysis and applies to a range of baselines and compounding laws.
