WebFeb 28, 2013 · all.cumulants takes moments of ordner n=0 to k as input. Since you require 4th order cumulants, I suspect you'll have to calculate raw moments upto 4th order and then compute all.cumulants. Does this sound right? If not, please leave a comment and I shall delete my answer. Share Improve this answer Follow edited Feb 28, 2013 at 11:34 WebAbstract: In this work, we point out some important properties of the normalized fourth-order cumulant (i.e., the kurtosis). In addition, we emphasize the relation between the signal distribution and the sign of the kurtosis.

Weband 4th cumulant functions are given by [6]: 2nd-order cumulant: (2) 4th-order cumulant: (3) Since the 4th cumulant is a multi-dimensional function, it is customary to use only 2D slices of it, by freezing some of the lags in Eq 3. In this paper, the horizontal slice is used by setting and : (4) The kurtosis is obtained by setting all lags to ...

WebDec 31, 2009 · Abstract: Let {X i} be a stationary dependent random process with finite eight-order moments. For broad classes of processes (¿-mixing and strongly mixing), we obtain the convergence in probability, with sharp rates, of the estimate of the fourth-order cumulant from n observations {X i} i=1 n.
