Webb27 okt. 2024 · Summary. In this lesson on how to find p-value (significance) in scikit-learn, we compared the p-value to the pre-defined significant level to see if we can reject the null hypothesis (threshold). If p-value ≤ significant level, we reject the null hypothesis (H 0) If p-value > significant level, we fail to reject the null hypothesis (H 0) We ...
