On the clustering of independent uniform random variables

Abstract: We consider the number K n of clusters at a distance level d n ∈ (0, 1) of n independent random variables uniformly distributed in [0,1] , or the number K n of connected components in the random interval graph generated by these variables and d n , and, depending upon how fast d n → 0 as n → ∞ , determine the asymptotic distribution of K n , with rates of convergence, and of related random variables that describe the cluster sizes.KEYWORDS: Clusters of independent uniform random variables, number and size of c… Show more

“…The focus here is on hierarchical clustering of variables, which is useful, for instance, to replace a class of closely related variables by a single representative, or a combination, for subsequent analysis [15]. The similarity between variables is typically measured by their correlation, although different proposals have been made in the literature depending on the nature of the considered variables (see, for instance, [19,3,12,23]).…”

“…Egy adott mintához és távolságszinthez tartozó osztályok számát nevezzük klaszterszámnak. Csörg® S. és Wu [23] három különböz® rátával nullához tartó távolságszint sorozat mellett bebizonyítot-ták a klaszterek számának aszimptotikus normalitását. Ennek a tételnek bizonyítjuk a többdimenziós változatait különböz® intervallumon egyenletes eloszlások esetében, majd használjuk egyenletesség tesztelésére ismert és ismeretlen intervallumon.…”
