Causal Polytree ---Pearl's classical algorithm(1988)
As a famous sub-structure of Bayesian network, causal polytree is able to recover the causality very efficiently.
Here, I implement pearl's classical algorithm here for easy using. Details can be seen in Pearl's paper[1].
To recover general Causal polytree, one can download "Fisher's exact test" in my space for conditional independence test.
One can start from ControlCenter.m, I add a simple example there for better understanding.
If there is any question, just let me know, I will response to you as soon as possible.
