| Abstract: | In this paper,we study a bivariate generalized Weibull distribution model by defining the marginals as the univariate generalized Weibull distribution.By using EM algorithm,we obtain the maximum likelihood estimators of the unknown parameters and the Fisher information matrix. |
| Keywords: | Weibull distribution maximum likelihood estimator EM algorithm Fisher information matrix |
