Evaluation of three methods for estimating the Weibull distribution parameters of Chinese pine (Pinus tabulaeformis )
Weibull distribution diameter distribution parameter estimation
2015/3/12
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 ...
The Beta Generalized Weibull distribution: Properties and applications
Weibull Beta Weibull distribution Generalized Weibull distribution Maximum likelihood estimation (MLE) Information matrix
2012/4/15
A five-parameter distribution called Beta Generalized Weibull (BGW) distribution is introduced. Beta Generalized Exponential (BGE), Beta Weibull (BW), Generalized or Exponentiated Weibull (GW or EW), ...
Fisher information matrix for three-parameter exponentiated-Weibull distribution under type II censoring
Fisher information three-parameter exponentiated Weibull distribution under type II censoring
2011/3/18
This paper considers the three-parameter exponentiated Weibull family under type II censoring. It first graphically illustrates the shape property of the hazard function. Then, it proposes a simple al...
Retailer's pricing and ordering strategy for Weibull distribution deterioration under trade credit in declining market
Finance Weibull deterioration trade credit
2010/9/21
In this research article, an ordering and pricing policy is formulated for a retailer when the supplier offers a delay in payments to settle the accounts against the retailer’s due. The problem is to ...
An EOQ model for deteriorating items with Weibull distribution deterioration, unit production cost with quadratic demand and shortages
Quadratic demand Weibull deterioration
2010/9/20
This article contains order level inventory models for deteriorating items with quadratic demand. The finite production rate is proportional to the demand rate and the deterioration is time proportion...
The impact of the Weibull distribution on the performance of the single-factor ANOVA model
ANOVA robustness Weibull ANOVA normality assumption Shape parameter Scale parameter Normality violation
2010/9/14
This paper conducts a simulation study of the effects of violating the ANOVA normality assumption in the presence of Weibull data. Twelve specific Weibull distributions, characterizing the life data o...
The effect of surface roughness on the Weibull distribution of porcelain strength
Weibull modulus Surface roughness Flexural strength
2010/11/26
The purpose of the present study was to test the hypothesis that glazing will affect the Weibull modulus or the mean flexural strength of dental porcelain. Four groups (n = 30) of specimens were prepa...
Parameters estimation of the modified Weibull distribution
Maximum likelihood least square linear failure rate
2010/9/10
Recently, Sarhan and Zaindin (2008) introduced a generalization of the Weibull distribution and named it as modified Weibull distribution. In this paper, we deal with the problem of estimating the par...
Statistical Analysis of Fracture Strength of Composite Materials Using Weibull Distribution
Weibull distribution Rapture strength Composite materials Carbon-epoxy
2009/10/13
In this study, the fracture strength of a carbon-epoxy composite plate has been statistically analysed by Weibull distribution. Nineteen tension tests were carried out. The results obtained vary betwe...

Optimal Conditional Confidence Interval for the Shape Parameter of a Weibull Distribution。
Effects of thermal cycling and surface roughness on the Weibull distribution of porcelain strength
Thermal cycling Weibull modulus Dental porcelain
2009/9/11
The objective of this study was to test the hypothesis that thermal cycling weakens the flexural strength of porcelain. Specimens of Deguceram Gold and Vita Omega 900 were tested in four groups of 30 ...
ESTIMATIONS OF THE PARAMETERS OF THE WEIBULL DISTRIBUTION WITH PROGRESSIVELY CENSORED DATA
Confidence interval Joint confidence region Maximum likelihood estimator Progressively type-II censored sample
2009/3/11
We obtained estimation results concerning a progressively type-II censored sample from a two-parameter Weibull distribution. The maximum likelihood method is used to derive the point estimators of the...
