摘要
///Higher-order statistics is an useful tool for studying non-Gaussian processes, nonlinear systems and non-minimum phase systems. Some problems, which cannot be solved satisfactorily using power spectrum or correlation functions, can be worthy of using higher-order statistics method. In this paper, the main theoretical results about applications of high-order statistics in geophysics are summarized.
