Topp–Leone Modified Weibull Model: Theory and Applications to Medical and Engineering Data

open access: yesApplied Sciences, 2022
In this article, a four parameter lifetime model called the Topp–Leone modified Weibull distribution is proposed. The suggested distribution can be considered as an alternative to Kumaraswamy Weibull, generalized modified Weibull, extend odd Weibull ...

Least squares fitting the three-parameter inverse Weibull density [PDF]

open access: yes, 2010
The inverse Weibull model was developed by Erto [10]. In practice, the unknown parameters of the appropriate inverse Weibull density are not known and must be estimated from a random sample.

Experimental Verification of the Weibull Distribution in a Reverberation Chamber

open access: yesInternational Journal of Antennas and Propagation, 2019
A Weibull distribution has been proposed for the probability density function (PDF) of the magnitude of the E-field in a reverberation chamber (RC). However, the Weibull distribution has two parameters, and if the parameters are position sensitive, the ...

Using weibull mixture distributions to model heterogeneous survival data [PDF]

open access: yes, 2003
In this article we use Bayesian methods to fit a Weibull mixture model with an unknown number of components to possibly right censored survival data. This is done using the recently developed, birth-death MCMC algorithm.

Bayesian Conditional Estimation of the Weibull Parameters Using Censored Data [PDF]

open access: yesThe Egyptian Statistical Journal, 1986
Analogous to the Weibull distribution, the conditional probability density function of the Weibull parameters and the unknown sample size n, are obtained, Also the Bayesian estimators of the unknown parameters are derived using the squared error loss ...

A Note on the Existence of the Location Parameter Estimate of the Three-Parameter Weibull Model Using the Weibull Plot [PDF]

open access: yesMathematical Problems in Engineering, 2018
The Weibull model is one of the widely used distributions in reliability engineering. For the parameter estimation of the Weibull model, there are several existing methods. The method of the maximum likelihood estimation among others is preferred because of its attractive statistical properties.

Gradation of filling materials of sand-gravel dams based on multi-dimensional probability distribution

open access: yesYantu gongcheng xuebao, 2022
The gradation and particle size of filling materials of sand-gravel dams determine the inter-particle contact relationship, and further affect the macro-mechanical response.
