welch_anova_test()
: Welch one-Way ANOVA test. A wrapper around the base function stats::oneway.test()
. This is is an alternative to the standard one-way ANOVA in the situation where the homogeneity of variance assumption is violated.friedman_effsize()
, computes the effect size of Friedman test using the Kendall’s W value.friedman_test()
, provides a pipe-friendly framework to perform a Friedman rank sum test, which is the non-parametric alternative to the one-way repeated measures ANOVA test.games_howell_test()
: Performs Games-Howell test, which is used to compare all possible combinations of group differences when the assumption of homogeneity of variances is violated.kruskal_effsize()
for computing effect size for Kruskal-Wallis test.p_round(), p_format(), p_mark_significant()
.wilcox_effsize()
added for computing effect size (r) for wilcoxon test.get_anova_table()
added to extract ANOVA table from anova_test()
results. Can apply sphericity correction automatically in the case of within-subject (repeated measures) designs.get_anova_label()
emmeans_test()
added for pairwise comparisons of estimated marginal means.comparison
removed from tukey_hsd()
results (breaking change).n
(sample count) added to statistical tests results: t_test()
, wilcox_test()
, sign_test()
, dunn_test()
and kruskal_test()
(@ShixiangWang, #4).rstatix_test
class added to anova_test()
resultskruskal_test()
is now an object of class rstatix_test
that has an attribute named args for holding the test arguments.get_y_position()
, y positions and test data are merged now for grouped plots.y.trans
added in get_y_position()
for y scale transformation.tukey_hsd()
results.adjust_pvalue()
now supports grouped dataget_pvalue_position
added to autocompute p-value positions for plotting significance using ggplot2.get_comparisons()
added to create a list of possible pairwise comparisons between groups.dunn_test()
added for multiple pairwise comparisons following Kruskal-Wallis test.sign_test()
added.get_summary_stats()
now supports type = “min”, “max”, “mean” or “median”t_test()
, wilcox_test()
, dunn_test()
and sign_test()
are now an object of class rstatix_test
that has an attribute named args for holding the test arguments.cohens_d()
is now a data frame containing the Cohen’s d and the magnitude.
