Weak convergence using higher-order cumulants

Journal of Theoretical Probability, 1992
Let \(c_ j(F)\) denote the \(j\)-th cumulant of the distribution function \(F\). The main result of the paper can be formulated as follows. Let \(\{F_ n\}\) be a sequence of distribution functions and let \(F\) be a distribution function which is specified by its higher-order cumulants (this notion is defined in the appropriate way, similar as in the ...

Higher order log-cumulants for texture analysis of PolSAR data

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
The log-cumulants of the second and third order are widely used to determine the statistical model of PolSAR data. However, same values of these statistics could result from both the product model and the mixture model, which represent two different physical scenarios.

DOA estimation via higher-order cumulants: a generalized approach

[Proceedings] ICASSP-92: 1992 IEEE International Conference on Acoustics, Speech, and Signal Processing, 1992
A general relation between the cumulant functions and the direction of arrival (DOA) parameters is developed. Using this relation it is shown that several DOA estimation algorithms can be obtained. One of these algorithms, involving the use of a Hankel matrix, is developed and its performance is studied in computer simulations. >

A fast algorithm for estimating higher-order cumulants

Proceedings of Third International Conference on Signal Processing (ICSP'96), 2002
In many problems of digital signal processing, it is required to estimate higher-order cumulants of a given process. We present a fast, inexpensive, and unbiased cumulant estimator. This estimator is based on, a polarity scheme. Unbiasedness is achieved by the addition of statistically independent auxiliary noise sources to the input signals.

Higher Order Asymptotic Cumulants of Studentized Estimators in Covariance Structures

Communications in Statistics - Simulation and Computation, 2008
In covariance structure analysis, the Studentized pivotal statistic of a parameter estimator is often used since the statistic is asymptotically normally distributed with mean zero and unit variance. For more accurate asymptotic distribution, the first and third asymptotic cumulants can be used to have the single-term Edgeworth, Cornish-Fisher, and ...
