I am able to calculate the confidence interval of each of their differences using prop. test() in R. However, the confidence intervals are likely overly narrow and p-values are inflated due to the multiple tests. My question is: if I were to use Bonferroni correction for this, I would change my alpha to be: $\alpha_{new} = \alpha/n = 0. 05/n$Description 计算比例对之间的成对比较,并进行多重测试校正 Usage pairwise . prop. test (x, n, p. adjust. method = p. adjust. methods, . ) Arguments Value "pairwise. htest" 类的对象 See Also prop. test, p. adjust Examples smokers <- c ( 83, 90, 129, 70 ) patients <- c ( 86, 93, 136, 82 ) pairwise . prop. test (smokers, patients)sign_test (): perform sign test to determine whether there is a median difference between paired or matched observations. anova_test (): an easy-to-use wrapper around car::Anova () to perform different types of ANOVA tests, including independent measures ANOVA, repeated measures ANOVA and mixed ANOVA. Description Calculate pairwise comparisons between pairs of proportions with correction for multiple testing Usage pairwise. prop. test (x, n, p. adjust. method = p. adjust. methods, . ) Arguments Value Object of class "pairwise. htest" prop. test, p. adjust Examples1 I'm trying to put together an R ggplot graph of some categorical data with pairwise p-values. I can graph the data, and work out the pairwise p-values, but can't work out how to display them together. Does anyone have any tips? My preference would be to display them using something like geom_signif (), but I'm completely stuck.

The length of p must be the same as the number . Description Calculate pairwise comparisons between pairs of proportions with correction for multiple testing Usage pairwise . prop. test (x, n, p. adjust. method = p. adjust. methods, . ) Arguments Value Object of class "pairwise. htest" See Also prop. test, p. adjust ExamplesFrom prop. test it seems that H0: pA = pB = pC H 0: p A = p B = p C could be rejected as probability of false discovery if there is no association is ~4%. However, as pairwise. prop. test shows there is no pair of groups where we could reject H0: pX = pY H 0: p X = p Y as Bonferroni corrected p-values are rather high. r. test. a single character string: which function to be called, choices are "prop. test" for the chi-square test, and "fisher. test" for Fishers exact test, as they are defined in package stats. …. arguments to be passed to prop. test (stats) or fisher. test (stats)Test of Equal or Given Proportions Description prop. test can be used for testing the null that the proportions (probabilities of success) in several groups are the same, or that they equal certain given values.

A one-way ANOVA uses the following null and alternative hypotheses: H0: All group means are equal. 2 Answers Sorted by: 2 As the pairwise documentation says your data must be a Vector of counts of successes or a matrix with 2 columns giving the counts of successes and failures, respectively If you reduce the number of columns to two as mentioned in the error, you would get a result. pairwise. prop. test (data [,c ("White","Black")])pairwise_prop_test R Documentation Pairwise Proportional Tests Description A tidy calculation of pairwise proportional comparisons between group levels with corrections for multiple testing Usage pairwise_prop_test (df, outcome, subgroups, vs_rest = FALSE, . ) Arguments Value A tibble with output from pairwise. prop. test Examples
