Schreiber, Tomasz, Variance asymptotics and central limit theorems for volumes of unions of random closed sets, Advances in applied probability , 34(3), 2002, pp. 520-539
Let X, X1, X2, . be a sequence of i.i.d. random closed subsets of a certain locally compact, Hausdorff and separable base space E. For a fixed normalised Borel measure . on E, we investigate the behaviour of random variables .(E \ (X1 . . . . . Xn)) for large n. The results obtained include a description of variance asymptotics, strong law of large numbers and a central limit theorem. As an example we give an application of the developed methods for asymptotic analysis of the mean width of convex hulls generated by uniform samples from a multidimensional ball. Another example deals with unions of random balls in .d with centres distributed according to a spherically-symmetric heavy-tailed law.
