| 摘 要： | 本文对一种新型中药降脂灵片的药效进行因果分析。实验数据样本量小且是混合变量类型,传统的统计方法难以处理,本文采用图模型的方法建立一个链图模型,直观地刻画了该药对反映机体抗氧化能力和血脂水平的4个指标的因果影响。 |
| 关 键 词： | 链图 条件Gauss分布 条件独立性 模型选择 |

| Abstract: | This paper made causal inferences for the efficacy of Jiailgzhiling tablet, a new type of Chinese medicine. Because of the small sample size and the mixed variable types, traditional statistical approaches can not give reliable results. In this paper, a chain graphical model was developed to describe the causal effect of Jiangzhiling on four variables which measured antioxidant capacity and blood fat level. |
| Keywords: | chain graph conditional Gaussian distribution conditional independence model Selection |
