Null Hypothesis in Conditoinal Independence Tests #166

Closed arainboldt closed 4 months ago

arainboldt commented 5 months ago

Hi!

What's the null hypothesis in the conditional independence tests? Is it independence or dependence?

e.g. https://github.com/py-why/causal-learn/blob/main/causallearn/utils/cit.py#L294

I'm trying to understand exactly how to interpret the p-value returned from the CIT methods.

Thanks!

Andrew

Hi, I think the null hypothesis is conditional independence.

This was my assumption. I just wanted to confirm. Thanks.
