中药降脂灵片药效的因果分析
Causal Analysis for the Efficacy of a Type of Chinese Medicine-Jiangzhiling Tablet
【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。
【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.
