FAILURE RATE OF THE WEIBULL-WEIBULL LENGTH-BIASED MIXTURE MODEL
by By S. A. Shaban and Naima Ahmed Boudrissa.
In this paper the failure rate of the Weibull-Weibull length-biased mixture
distribution which is characterized by five parameters is studied. Depending
on the parameter values, it is shown that this failure rate can have one of
six shapes, which are increasing failure rate (IFR), decreasing failure rate
(DFR), upside down bathtub (UBT), modified upside down bathtub (MUBT), bathtub
(BT), and modified bathtub (MBT) failure rates, by consequence it has zero,one
or two turning points.
