The p-value for this hypothesis test is
WebbThis means that we want the following to be true if the null hypothesis is true: P r ( p < α) = α This is just the CDF of the continuous standard uniform distribution. A clear deviation from the uniform distribution is an indication that your null hypothesis is to be rejected. Webb30 okt. 2016 · If the null hypothesis is true, we expect T to be 0. You have observed T = 3.27. So the P-value is P ( T > 3.27) + P ( T < − 3.27). The second term is because -3.27 …

Webb27 sep. 2016 · When you set test="Rao", it gives you the p-value from a score test. And when you set either test="Chisq" or test="LRT" (they are the same), it gives you the p-value from a likelihood ratio test. The anova.glm() function does test the same null hypothesis as the Wald test in the summary() output in this case. Webb15 okt. 2024 · A p-value (short for probability value) is a probability used in hypothesis testing. It represents the probability of observing sample data that is at least as extreme …
