The Kuiper test compares two ECDFs by looking at the maximum positive and negative difference between them. Formally – if E is the ECDF of sample 1 and F is the ECDF of sample 2, then KUIPER=∣maxxE(x)−F(x)∣p+∣maxxF(x)−E(x)∣pKUIPER = |max_x E(x)-F(x)|p + |max_x F(x) .

What is MANOVA (Multivariate Analysis of Variance)? MANOVA is an extension to univariate ANOVA that includes at least two dependent variables to analyze differences between multiple groups in the independent variable. In contrast to ANOVA, where we compare individual group means, MANOVA compares the vectors. The post MANOVA(Multivariate Analysis of . You can find the complete R code used in this tutorial here.

Here, HZ is the value of the Henze-Zirkler’s test statistic at significance level \(0.05\) and p-value is the significance value of this test statistic, i.e., the significance of multivariate normality. As the p-value, which is derived from hzTest, is mathematically lower than \(0.05\), one can conclude that this multivariate data set deviates slightly from multivariate normality .

Kuiper Test of Circular Uniformity Description. Kuiper's test statistic is a rotation-invariant Kolmogorov-type test statistic. The critical values of a modified Kuiper's test statistic are used according to the tabulation given in Stephens (1970). Usage kuiper_test(x, alpha = 0, axial = TRUE) Arguments In this paper, the performance of six types of techniques for comparisons of means is examined. These six emerge from the distinction between the method employed (hypothesis testing, model selection using information criteria, or Bayesian model selection) and the set of hypotheses that is investigated (a classical, exploration-based set of hypotheses containing .cvm_test(): Permutation based two sample Cramer-Von Mises test cvm_stat(): Permutation based two sample Cramer-Von Mises test See Also. dts_test() for a more powerful test statistic. See ks_test() or kuiper_test() for the predecessors to this test statistic. See wass_test() and ad_test() for the successors to this test statistic. ExamplesAssumptions of MANOVA. MANOVA can be used in certain conditions: The dependent variables should be normally distribute within groups. The R function mshapiro.test( )[in the mvnormtest package] can be used to perform the Shapiro-Wilk test for multivariate normality. This is useful in the case of MANOVA, which assumes multivariate normality.. Homogeneity of variances .

The assumption that multivariate data are (multivariate) normally distributed is central to many statistical techniques. The need to test the validity of this assumption is of paramount importance, and a number of tests are available.A recently released R package, MVN, by Korkmaz et al. (2014) brings together several of these procedures in a friendly and .
I am trying to implement a kuiper's test on a set of data and looking for an R package (or other program) that can give a p-value without monte carlo simulation or only a range of p-values. All of the packages (listed below) either give ranges of p-values or simulate (very limited because of time for simulation).
