TLDR
In this article, a simple generalization of the Weibull distribution is presented, which is well suited for modeling bathtub failure rate lifetime data and for testing goodness-of-fit of the weibull and negative exponential models as subhypotheses.Abstract:

Likelihood Maximization of Lifetime Distributions With Bathtub-Shaped Failure Rate
TL;DR: In this paper , a multistart nonlinear optimization algorithm was proposed to fit lifetime distributions with bathtub-shaped failure rate to data by the maximum likelihood criterion, which yields better fits than those reported in the literature in 14 out of 19 distribution-dataset pairs.

The Yun transform in probabilistic and statistical contexts: Weibull baseline case and its applications in reliability theory
TL;DR: In this paper, the authors proposed a new three-parameter distribution from this family, namely the Yun-Weibull (YW) distribution, based on a particular case of a transform introduced by Yun (2014).

Lifetime Prediction Model of IGBT Modules in EMU
TL;DR: The IGBT life prediction model is established according to the Weibull distribution obtained by this experiment, which proved that loss on free-wheeling diode accelerated the IGBT aging.

The Generalized Gamma – Exponentiated Weibull Distribution with its Properties
TL;DR: In this paper, the cumulative distribution, probability density, reliability and hazard rate functions are introduced, and most vital statistical properties, for instance, the r-th moment, characteristic function, quantile function, simulated data, Shannon and relative entropies besides the stress-strength model are obtained.

Statistical Models and Methods for Lifetime Data
TL;DR: Inference procedures for Log-Location-Scale Distributions as discussed by the authors have been used for estimating likelihood and estimating function methods. But they have not yet been applied to the estimation of likelihood.
