摘要
讨论二元寿命分布的识别性及参数估计,仅是最小值的分布已知时,只有一个参数可识别,当可识最小值的分布已知时,所有参数皆可识别;由此得到了所有参数的最大似然估计.
This paper shows： if two random variable have some bivariate life distributions when the distribution of the minimum is known, then only one of parameters is identified when distribution of the identified minimum is known, then all of parameters are identified hence, the maximum likelihood estimator of all of parameters are derived.
