Abstract: |
In this paper, we study the problems on existence and convergence of maximum likelihood estimation of parameters in Lomax distribution. Using a strict analysis method and the center limit theorem, we obtain some results that the maximum likelihood estimation of parameters in Lomax distribution exists, and the estimators are the asymptotic normal distribution. Further promoting to the situations in two Lomax populations with partially missing data, the maximum likelihood estimations possess the strong consistency and asymptotic normality. |
