Williams (1955) and Bartlett (1951) have derived some exact tests for the goodness of fit of a single hypothetical function to bring out adequately the entire relationship between two vectors x and y, by factorizing Wilks' lambda suitably. These factors are known as 'direction' and '...
Cross-Correlation of Two Vectors Create a vectorxand a vectorythat is equal toxshifted by 5 elements to the right. Compute and plot the estimated cross-correlation ofxandy. The largest spike occurs at the lag value when the elements ofxandymatch exactly (-5). ...
A measure of multivariate correlation between two sets of vectors is considered when the underlying joint distribution is a member of the class of elliptical distributions. Its asymptotic distribution is derived under different situations and these results are used to test hypotheses on vector ...
Fig. 11.4.The lowly dot product. For two vectors, the dot product is the sum of the products of the corresponding values. To normalize the dot product, we would divide the dot product by the product of the lengths of the two vectors. ...

For centered data (i.e., data which have been shifted by the sample mean so as to have an average of zero), the correlation coefficient can also be viewed as the cosine of the angle between the two vectors of samples drawn from the two random variables (see below). Some practitioners ...
Its asymptotic distribution is derived under the null hypothesis of no association between the random vectors and under a sequence of alternatives. A procedure is described for performing a nonparametric test of no association between two random vectors and an empirical comparison is performed with ...
(2) to p vectors to handle multivariate situations. The correlation matrix {rij} is a multivariate descriptive statistics between two or more variables which is free from units of measurement. That is, it is invariant under any linear transformation. Computation of the correlation matrix is ...
