摘　　要：讨论二元Friday-Patil型指数分布的多元形式,以及对应的多元指数分布的特征与参数估计.利用分布密度函数等价分拆思想,导出了二元Friday-Patil型指数分布的多元推广,得到了多元Friday-Patil型指数分布的特征,并利用该特征获得了相应参数的最大似然估计及矩估计.因此,多元Friday-Patil型指数分布是一个有特征的混合型分布.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.
