研究了多个 kotz 分布总体的参数基于序约束下的极大似然估计问题，并给出了多个 kotz 分布总体未知参数的极大似然估计的算法，根据PAVA算法又给出了k个kotz分布总体的参数在简单半序，伞形半序，简单树半序和简单环半序约束下的极大似然估计。还讨论了多个kotz分布总体参数基于截尾样本的极大似然估计的计算方法。%Maximum likelihood estimation of parameters of multiple Kotz-type distribution based on order restrictions was studied. The method about the maximum likelihood estimation of the unknown parameters of the multiple Kotz-type distribution was given. Based on the PAVA algorithm,maximum likelihood estimation of parameters of k Kotz-type distribution based on order restrictions was given too, such as, simple order, umbrella semi-order, simple tree order and simple ring order. Maximum likelihood estimation of parameters of multiple Kotz-type distribution based on censored samples was discussed.
