Due to the flexibility of the Weibull distribution and the proportional hazard (PH) model, Weibull PH is widely used in survival analysis under right censored data and interval censored data but it is seldom investigated under current status data ...

Classical and Bayesian estimation for type-I extended-F family with an actuarial application.
In this work, a new flexible class, called the type-I extended-F family, is proposed. A special sub-model of the proposed class, called type-I extended-Weibull (TIEx-W) distribution, is explored in detail.

The Burr X Exponentiated Weibull Model: Characterizations, Mathematical Properties and Applications to Failure and Survival Times Data [PDF]
In this article, we introduce a new three-parameter lifetime model called the Burr X exponentiated Weibull model. The major justification for the practicality of the new lifetime model is based on the wider use of the exponentiated Weibull and Weibull ...

Robust fitting of a Weibull model with optional censoring [PDF]
The Weibull family is widely used to model failure data, or lifetime data, although the classical two-parameter Weibull distribution is limited to positive data and monotone failure rate. The parameters of the Weibull model are commonly obtained by maximum likelihood estimation; however, it is well-known that this estimator is not robust when dealing ...

Gradation characteristics and envelope curve design method for natural sandy gravel
Due to the limitation of the number of samples, the particle-size envelope method for directly determining the sand-gravel design line according to the gradation curve of exploration stockyard is difficult to reasonably reflect the actual gradation range
