In statistics, the Kruskald-deOCtWallis one-way analysis of variance by ranks (named after William Kruskal and W. Allen Wallis) is a non-parametric method for testing equality of population medians among groups. It is identical to a one-way analysis of variance with the data replaced by their...

Statistic fundamentals of he Correspondence Analysis (CA) is presented in the CORRAN m-file you can find in this FEX author''s page. CA can be extended, a this m-file makes, to more than two categorical variables, called Multiple Correspondence Analysis (MCA).Karl Pearson (1913) developed the...

Other hypothesis used with the Mauchly's sphericity test is on the orthonormalized contrasts,H0: Cd-deOaoSC = s^2I , where C is any full-rank (p-1) x p matrix of orthonormal contrasts.A is the nonorthonormalized contrasts matrix.C = GMO(Ad-deOao) is a (p-1) doOCo p column-orthonormal matrix (by...

Doornik-Hansen (1994) introduce a multivariate version of the univariate omnibus test for normality of Shenton and Bowman (1977), based on the transformed skewness and kurtosis. Due that the skewness and kurtosis are not independently distributed and the kurtosis approaches very slowly to...

Calculates the Mardia's multivariate skewness and kurtosis coefficients as well as their corresponding statistical tests. For large sample size the multivariate skewness is asymptotically distributed as a Chi-square random variable; here it is corrected for small sample size. Likewise, the...

A statistical analysis used for count data is to compare the proportions of a binary outcome of interest for two or more groups.This m-file it is an implemented alternative to the Marascuillo's test and identifies significant pairwise contrasts that this last one does not. If the previously...

Grubb's outlier test can be used to remove one outlier (see deleteoutliers.m by Brett Schoelson). If you decide to remove this outlier, you might be tempted to run Grubbs' test again to see if there is a second outlier in your data. However, if you do this, you cannot use the same rejection...

On the literature there are available several tests of the multivariate normality (ca. 50). Among them is the graphic approach based on a chi-square quantile-quantile plot of the observations' squared Mahalanobis distances. Besides the graphic q-q approaching, in this file we proposes an...

From the covariance matrices (without data), groups size vector and a significance level (default = 0.05), the homogeneity covariance matrices are testing by the Box's M, it gives a Chi-square or F approximation in function of the groups sample-size.Outputs are the Box's M statistic,...

This m-file performs the Cochran's Q test for multi-way tables which each variable has two levels, that is, for 2x2...x2 tables. It is used to test the homogeneity of the one-dimensional margins. So, Cochran's Q test is a nonparametric test examining change in a dichotomous variable across more...

This m-file performs the Bowker's test for symmetry. It is an extension of the McNemar test to a KxK situation. There are now K response categories for the two dependent samples.The null hypothesis is that the probabilities in the square table satisfy symmetry or that there is no sifnificant...

Computes the interrelationships between two sets of variables made on the same objects without data. The canonical correlation is the maximum correlation between linear functions of the two vector variables. Linearity is important because the analysis is performed on the correlation matrix which...

From a total multivariate data matrix and a significance level, the homogeneity covariance matrices are testing by the Box's M, given a Chi-square or F approximation in function of the group sample-size.

Correspondence Analysis (CA) is a special case of Canonical Correlation Analysis (CCA), where one set of entries (categories rather than variables) is related to another set. Also, it can be seen as a special case of Principal Component Analysis (PCA), where it is used for tables consisting of...

This file performs the Fisher exact probability test for a table of frequency data cross-classified according to two categorical variables, each of which has two levels or subcategories (2x2). It is a non-parametric statistical test used to determine if there are nonrandom associations between...
