How does SearchGraphUtils.patternForDag method work? #231

Closed haluk closed 8 years ago

haluk commented 8 years ago

Why do we use patternForDag method to compare true network and learnt one?

jdramsey commented 8 years ago

Because a method like PC doesn't output a DAG; it outputs a pattern. Some of the edges are undirected. If you compare it the true DAG, you will penalize the result for not orienting some edges. But it's not supposed to!
