WebApr 19, 2024 · In this paper, we prove that conditional independence is indeed a particularly difficult hypothesis to test for. Valid statistical tests are required to have a size that is smaller than a predefined significance level, and different tests usually have power against a different class of alternatives. WebThe big idea is that we check for independence with probabilities. Two events, A and B, are independent if P (\text {A } \text { B})=P (\text {A}) P (A ∣ B) = P (A) and P (\text {B } \text { A})=P (\text {B}) P (B ∣ A) = P (B).
