Critical Appraisal Of Statistics In Health Science Lecture 8 Part 2 Patreon professorleonardstatistics lecture 8.3: hypothesis testing for population proportion. testing a claim about a population proportion. Statistical tests signal & background. the probability to reject a background hypothesis for background events is called the background efficiency: 1. b = g(t; b)dt = ↵. tcut. the probability to accept a signal event as signal is the signal efficiency: s = z g(t; s)dt = 1. tcut. Empirical risk minimization. 1. pattern classification: θ : x → {0, 1}, z = (x, y) ∈ x × {0, 1}, l(θ, (x, y)) = 1[θ(x) 6= y]. empirical risk minimization chooses θ to minimize misclassifications on the sample. 2. density estimation: p is a density, x. erm is maximum likelihood. ∼ p , p , l(θ, z) = − log θ∗ pθ(z). The area to the left of the critical value \(z {\alpha 2}\) and to the right of the critical value \(z {1 \alpha 2}\) is called the critical or rejection region. see figure 8 9. figure 8 9. when \(\alpha\) = 0.05 then the critical values \(z {\alpha 2}\) and \(z {1 \alpha 2}\) are found using the following technology.
