| Abstract: | The present paper deals with the asymptotic properties of estimation and likelihood ratio test for two lognormal populations with partially missing data.The limit distributions of estimators and likelihood ratio test are given,the strong consistency of estimators is also proved. |
| |
| Keywords: | missing data maximum likelihood estimation test for likelihood-ratio limit distribution |
