✦ Synopsis
Reciprocity and other social interaction patterns can be studied at two levels, within pairs (i.e. at dyadic level) and among pairs (i.e. at group level). In this paper advantages of the latter approach are emphasized. However, an analysis at group level implies the correlation of interaction matrices and because such data are statistically dependent, the significance of a correlation has to be calculated in a special way. This is done by means of Mantel's permutation procedure. In order to reckon with individual variation, Mantel's permutation procedure is used in combination with the so-called Kr statistic, whereby correlations are calculated simultaneously for each separate row. With the aid of the Kr test, the correlation for interchange of grooming for the receipt of "'support" in conflicts in baboons and
