Description

The Inverse Weibull distribution is one of the widely-applied distributions. In this paper, we are going to extend the study of the Beta Inverse Weibull Distribution (BIW). We are going to investigate the parameter estimation of BIW distribution. Determined by three parameters, the BIW distribution has a relatively complicated form, which causes difficulties for parameter estimation. The Maximum Likelihood Estimation (MLE) procedure is implemented in the BIW distribution with three parameters. In computation, the Newton-Raphson method is applied using single and multiple initializations, the steepest descent method is also implemented using single and multiple initializations, and the simulation results are given. Finally, practical use of the methods is demonstrated by using an application to real data.
