            摘要:
長久以來,有關隨機序的估計問題一直被廣泛的討論與應用,然而在許多實際的應用上,我們發現兩組多項式分配的參數p和q除了隨機之外,可能還有其他的關係,例如相等、相差一個常數,或是成倍數關係。我們對參數了解愈多,愈能夠得到更精確的估計,因而在文章中,我們仿效Barlow及Brunk(1972)的方法推得在隨機序與部分等式條件下,多項式參數的最大概似估計。我們依單樣本和雙樣本分別討論並提供應用實例,此外我們也探討估計的一致性問題。
            關鍵詞:多項式參數、最大概似估計、隨機序、最小平方投影

            Abstract:
The problems of maximum likelihood estimates of multinomial parameters subject to stochastic ordering have been widely discussed. However, in some applications, the multinomial parameters p and q may not only satisfy the stochastically ordered constraints but also the equality of some of these parameters. We follow Barlow and Brunk's method (1972) and obtain the Fenchel duality projection-type maximum likelihood estimates of multinomial parameters under this modified hypothesis for both one-sample and two-sample problems. The consistency of the estimates is proved and. an example is also presented as an illustration.
