本文提出了一种当数据按两个因素分类时两个比率之间的差异的分解方法，对于所考虑的事件，其中一个因素可能被认为是比另一个因素更直接的因素。这两个因素被视为分层的，因此该方法在概念上不同于 Kitakawa (1955) 和 Das Gupta (1978) 的分解方法，其中两个因素被视为对称的。我们的方法被证明是 Cho-Retherford (1973) 分解方法的平衡版本。以使用我们的方法对新生儿死亡率进行的分析为例。
A decomposition method for the difference between two rates when data are classified by two factors, one of which may be considered as a more direct factor than the other for the event under consideration, is presented in this paper. The two factors are treated as hierarchical and thus this method is conceptually different from the decomposition methods of Kitagawa (1955) and Das Gupta (1978), in which two factors are treated as symmetrical. Our method is shown to be a balanced version of the Cho-Retherford (1973) decomposition method. Analyses of neonatal mortality rates using our method are presented as an example.
