Abstract
    In this paper, we give the generalization hierarchical cluster recurrence formulas for nearest-neighbour method, furthest-neighbour method, average linkage method, median method, centroid method, group-average method, sum of squares method, flexible method and flexible group average methods, respectively, and an united computing formula of these clustering methods are also obtained.
