摘要:

我们描述了一种方法,该方法推断两个观测变量X和Y之间的统计依赖性是由于“直接”因果联系还是仅仅由于包含低复杂度的未观测变量的连接因果路径,例如,二进制变量。这个问题的动机是统计遗传学。给定与感兴趣的表型相关的遗传标记,我们希望检测该标记是因果关系还是仅与因果关系相关。我们的方法是基于对条件分布P(Y)的位置的分析|x)在Y的所有分布的单形中。我们报告令人鼓舞的结果半经验数据。

英文摘要:

We describe a method that infers whether statistical dependences between two observed variables X and Y are due to a "direct" causal link or only due to a connecting causal path that contains an unobserved variable of low complexity, e.g., a binary variable. This problem is motivated by statistical genetics. Given a genetic marker that is correlated with a phenotype of interest, we want to detect whether this marker is causal or it only correlates with a causal one. Our method is based on the analysis of the location of the conditional distributions P(Y|x) in the simplex of all distributions of Y. We report encouraging results on semi-empirical data.
