  - Proportional link linkage (PLL) clustering methods are a parametric family of
    monotone invariant agglomerative hierarchical clustering methods. This family
    includes the single, minimedian, and complete linkage clustering methods as special
    cases; its members are used in psychological and ecological applications. Since
    the literature on clustering space distortion is oriented to quantitative input
    data, we adapt its basic concepts to input data with only ordinal significance
    and analyze the space distortion properties of PLL methods. To enable PLL methods
    to be used when the numbern of objects being clustered is large, we describe an
    efficient PLL algorithm that operates inO(n 2 logn) time andO(n 2) space@eng
