The unusual properties of aggregated superpositions of Ornstein–Uhlenbeck type processes
Danijel Grahovac, Nikolai N. Leonenko, Alla Sikorskii, and Murad S. Taqqu
Abstract
Superpositions of Ornstein–Uhlenbeck type (supOU) processes form a rich class of stationary processes with a flexible dependence structure. The asymptotic behavior of the integrated and partial sum supOU processes can be, however, unusual. Their cumulants and moments turn out to have an unexpected rate of growth. We identify the property of fast growth of moments or cumulants as intermittency. Many proofs are given in a supplemental article (Grahovac, Leonenko, Sikorskii and Taqqu (2018)).
