1PE: prediction error, under the hypothesis that prediction is correct, PE follows a χ² law with 10 degrees of freedom; that is, with a 5% α-risk, if PE >18.3 then the prediction is not correct for that Département. 2χ² with one degree of freedom, threshold value 3.84. 3RE: relative error; that is, predicted cases-observed cases/observed. |
