A STUDY OF A GENERALIZED MODIFIED WEIBULL MODEL: AN EXPONENTIATED WEIBULL CASE
Han Wu, Mezbahur Rahman and Mohammad Shaha Alam Patwary
|
Abstract: A generalization of the Weibull distribution has been proposed by Carrasco et al. [1] to model lifetime problems and reliability. To further investigate the model, maximum likelihood estimates and the observed information matrix are obtained to compute the standard errors of the estimates. The Newton-Raphson algorithm is implemented and the explicit expressions are given. Two examples are provided to illustrate the results. |
