LIMITING BEHAVIOR OF WEIGHTED SUMS OF HEAVY-TAILED
RANDOM VECTORS AND APPLICATIONS

Abstract: We present an integral test to determine the limiting behavior of weighted sums of
i.i.d. -valued random vectors belonging to the (generalized) domain of operator
semistable attraction of some nonnormal law, and deduce a version of Chover’s law of the
iterated logarithm for them. As applications, the corresponding limit results for some
classical summability methods are also established.
