Web1 day ago · PZMs in 6/48 (13%) tissues were significantly less deleterious than the average tissue, and PZMs in 3/48 (6%) tissues were more deleterious (Q < 0.05, Wald test). When analyzed together, the PZMs from all brain regions were also more deleterious than average (P = 0.02, Fisher’s exact test). WebIn practice, the results of a poor normal approximation tend to be intervals that include values outside the range of (0,1), which we know cannot apply to \(\pi\). The score interval performs better than the Wald in these situations because it …

WebThe Corrected Wald interval uses a continuity correction included in the test statistic. The continuity correction is subtracted from the numerator of the test statistic if the numerator is greater than zero; otherwise, the continuity correction is added to the numerator. The value of the continuity correction is (1/n1 + 1/n2)/2. WebThe Agresti-Coull confidence interval has the same basic form as the standard Wald interval but uses in place of .
