THE WEIBULL LENGTH BIASED DISTRIBUTION
-PROPERTIES AND ESTIMATION-
By: S. A. Shaban, Naima Ahmed Boudrissa.
The length-biased version of the Weibull distribution known
as Weibull length-biased (WLB) distribution is considered, it is shown
that it is unimodal throughout examining its shape. Other properties of
the distribution were studied such as the moments, and the hazard rate
function. It is shown that the hazard function is upside bathtub shaped
for values of the shape parameter that are less than unity and increasing
otherwise. Bayesian and non Bayesian estimation problems are also considered.
A numerical example is introduced for illustration.
