Structuring Causal Tree Models with Continuous Variables

  title={Structuring Causal Tree Models with Continuous Variables},
  author={Lei Xu and Judea Pearl},
This paper considers the problem of invoking auxiliary, unobservable variables to facilitate the structuring of causal tree models for a given set of continuous variables. Paralleling the treatment of bi-valued variables in [Pearl 1986], we show that if a collection of coupled variables are governed by a joint normal distribution and a tree-structured… CONTINUE READING
