Computes the matrix of the symmetric Chi-squared distances between several multivariate or univariate discrete probability distributions on the same support (which can be a Cartesian product of \(q\) sets), given the probabilities of the states (which are \(q\)-tuples) of the support.
matddchisqsympar(freq)Positive symmetric matrix whose order is equal to the number of distributions, consisting of the pairwise symmetric chi-squared distances between these distributions.
list of arrays. Their dim attribute is a vector with length \(q\), its elements containing the numbers of levels of the \(sets\). Each array contains the probabilities of the discrete distribution on the same support.
