Parametric inference on partially accelerated life testing for the inverted Kumaraswamy distribution based on Type-II progressive censoring data

Mathematical Biosciences and Engineering, 2023
This article discusses the problem of estimation with step stress partially accelerated life tests using Type-II progressively censored samples. The lifetime of items under use condition follows the two-parameters inverted Kumaraswamy distribution.

Applicability of modified weibull extension distribution in modeling censored medical datasets: a bayesian perspective [PDF]

Scientific Reports, 2022
There are some contributions analyzing the censored medical datasets using modifications of the conventional lifetime distribution; however most of the said contributions did not considered the modification of the Weibull distribution (WD).

BAYES ESTIMATOR OF GENERALIZEDEXPONENTIAL PARAMETERS UNDER GENERAL ENTROPYOSS FUNCTION USING LINDLEY’S APPROXIMATION

Statistics in Transition new series, 2009
In this paper, we have obtained the Bayes Estimator of scale and shape parameter of Generalized-Exponential using Lindley’s approximation (L-approximation) under GENERAL ENTROPY loss functions. The proposed estimators have been compared with the corresponding MLE for their risks based on simulated samples from the Generalized-Exponential distribution.

Lindley Approximation Technique for the Parameters of Lomax Distribution [PDF]

International Journal of Statistics in Medical Research, 2017
The present study is concerned with the estimation of shape and scale parameter of Lomax distribution using Bayesian approximation techniques (Lindley’s Approximation). Different priors viz gamma, exponential and Levy priors are used to obtain the Bayes estimates of parameters of Lomax distributions under Lindley approximation technique.

Optimizing ridge regression through Bayesian estimators: a Lindley's approximation study

Journal of Statistical Computation and Simulation
In linear regression modelling, it is crucial for the explanatory variables to be uncorrelated with each other; however, this assumption is often violated. When the explanatory variables are highly multicollinear, the ordinary least squares (OLS) estimator can yield estimates with larger variances.

Lindley’s Approximation in Estimating Two-Parameters Inverted Weighted Exponential Distribution

Universiti Malaysia Terengganu Journal of Undergraduate Research
The Inverted Weighted Exponential 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 Bayesian approach to estimate the two parameters of the distribution.

Inference and Optimal Design on Partially Accelerated Life Tests for the Power Half-Logistic Distribution Under Adaptive Type II Progressive Censoring

Mathematics
This study explores accelerated life tests to examine the durability of highly reliable products. These tests involve applying higher stress levels, such as increased temperature, voltage, or pressure, that cause early failures.
