In this paper,with respect to the ordinal variables,the definitions of attribute reduction of dominance-based rough set approach in ordered information systems and ordered decision tables are given.Then the approach of sorting objects comprehensively using rough set theory is brought in to obtain a series of ranks.Based on these ranks,nonparametric methods to analyze correlation between two attribute subsets are introduced,and Spearman rank correlation coefficient is used as a measure of attribute correlation.Based on this measure,a new method of attribute reduction of ordered information systems and ordered decision tables is presented without changing the ordinal information of the universe.
针对有序尺度变量,给出了有序信息系统与有序决策表在优势关系下的粗糙集约简定义;利用粗糙集方法将对象综合排序,进而得到一组秩;根据这些秩,运用非参数统计的思想研究了两个属性子集之间的相关性,并将Spearman秩相关系数作为属性相关性度量;在不改变总体序信息情况下,给出了基于此度量对有序信息系统与有序决策表进行约简的新方法。

In statistical analysis of ordinal data, we usually build up linear-by-linear association model and meet a trouble of choice of scores. Graubards et a1 (1987) proposed several methods for score choice in independence test in ordinal 2×κ contingency tables: equally spaced scores, midpoint scores and midrank scores. He also pointed out that the result of independence test may be different for the different choice of scores according to the same association model. Agresti et a1 (1987) treated the score vector in row effects and column effects model for two-way contingency tables as parameters and derived the necessary and sufficient condition of the solution under monotone order restriction by Kuhn- Tucker conditions.
在有序数据的统计分析中,通常要建立线线相关模型,其中得分的选取是一个棘手的问题,Graubard et a1(1987)给出了有序2×κ列联表中独立性检验的几种得分选取方法:等距离得分,中点得分和midrank得分等,同时指出,对于同一个相关模型,独立性的检验会由于得分选取的不同而得到不同的结论,Agresti et al(1987)把二维列联表中的行效应和列效应模型中的得分向量作为参数,在满足递增的序关系情况下,利用Kuhn-Tucker条件给出了解的充要条件。

Although translator has turned from being a crystal ball by which the original culture can unrestrainedly penetrate to another crystal ball by which the target culture can freely traverse, the translator's personal embodiment, in the process of cognitive act, are still absent in translation studies. Translators are still subjects without body or simply disembodied subjects.
