Abstract

This research addressed the problem of estimating scale parameter and reliability function for the two parameters Wiebull distribution through the use of a variety of loss functions of the Baysian method and compares it with the standard Baysian method using the simulation, where the generation of random data, depending on the sample sizes (n=25,50,100) and run size (N=1000) , taking default values for the shape parameter as a constant value and known , the presumption of the value of a scale parameter is unknown, as it took several values are . To make comparison between the preferences of these methods mean square error (MSE) was used.
