帶相依結(jié)構(gòu)的二維列聯(lián)表的多重比較
發(fā)布時間:2021-07-09 20:38
列聯(lián)表是一種常見的數(shù)據(jù)存儲格式,其中的數(shù)據(jù)是將觀測數(shù)據(jù)按兩個或者更多屬性進行分類后的頻數(shù)。列聯(lián)表常用于醫(yī)學、生物學、社會科學等學科之中。通過對列聯(lián)表進行統(tǒng)計分析,可以考察各個屬性之間是否有聯(lián)系,也就是判斷兩個屬性變量是否具有獨立性.可用于檢驗列聯(lián)表中的兩個屬性變量的獨立性的假設(shè)檢驗方法有:卡方獨立檢驗、Fisher精確檢驗、Cochran-Mantel-Haenszel檢驗[1]等。本文的目的是建立一個模型,進而基于這個模型提出一個新的檢驗方法,用于檢驗列聯(lián)表的屬性變量的獨立性,這個模型也可以衡量兩個屬性變量的(正、負)相關(guān)性。本文的整體思路是通過引入一個可以衡量變量相關(guān)性的參數(shù),構(gòu)造一個二元二項分布,并將它用于對二維列聯(lián)表的統(tǒng)計分析。在緒論中,我們總結(jié)了文獻中已有的二元二項分布。假設(shè)隨機向量(X,Y)服從二元二項分布,且兩個邊際分布都是二項分布,即X~Binomial(n1,π2)和Y~Binomial(n2,π2)。文獻中已有的二元二項分布大致可以分成三類:第一種是要求n1與n2相等,即n1=n2=n;第二種是要求π1和π2相等,即π1=π2=π;第三種對n1,n2和π1,π2不做...
