WebAug 27, 2015 · P = P ( 1) ( X ≥ q α ( 0)) Where the superindex ( 1) indicates that the probabilities are computed under F ( 1) So the power is measured with F ( 1) but you need … WebThe easiest way to think about Type 1 and Type 2 errors is in relation to medical tests. A type 1 error is where the person doesn't have the disease, but the test says they do (false positive). A type 2 error is where the person has the disease but the test doesn't pick it up (false negative). 3 comments ( 144 votes) Upvote Flag Show more...
