WebDec 22, 2014 · pchisq(deviance(spray0)-deviance(spray1), df.residual(spray0)-df.residual(spray1), lower.tail=FALSE) --Many people would use the comparison between full and null-model AIC (or in some cases, perhaps a comparison between a model of interest and the saturated model) to work out whether the model was better than the null in that … WebAlternative Solution 1 Instead of using the critical value, we apply the pnorm function to compute the lower tail p-value of the test statistic. As it turns out to be greater than the .05 significance level, we do not reject the null hypothesis that p ≥ 0.6 . > pval = pnorm (z) > pval # lower tail p − value [1] 0.26187 Alternative Solution 2

WebAug 24, 2024 · The reason for the x - 1 is the discreteness of the Poisson distribution (that’s the way lower.tail = FALSE works). There is no exact two-tailed because the exact (Poisson) distribution is not symmetric, so there is no reason to us \(\lvert X - … Weblower.tail logical; if TRUE (default), probabilities are P[X ≤ x], otherwise, P[X > x].* In other words, when lower.tail=FALSE you get the probability to the right of X (the first of your two diagrams).
