摘要:

Ornstein-Uhlenbeck型过程的叠加形成了一类丰富的平稳过程,具有灵活的依赖结构。然而,积分过程和部分和叠加过程的渐近行为可能是不寻常的。它们的累积量和矩的增长速度出人意料。我们确定的矩或累积量的快速增长的属性为不连续性。

英文摘要:

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.
