| Abstract: | The article discusses the multivariate extension of the bivariate exponential distribution of Friday- Patil, and characterization and parameter estimation of the multivariate exponential distribution of Friday-Patil are presented. Based on the method of partitioning technique of distribution density, the maximum likelihood estimators and the moment estimators of parameters of the Friday-Patil type＇s multivariate exponential distribution are obtained. The conclusion can finally be made that the Friday-Patil type＇s multivariate exponential distribution is a mixed type exponential distribution with its characteristics. |
