On estimation of the integrals of the fourth order cumulant spectral density
Department of Applied Mathematics, Hiroshima University Japan
It is known that the asymptotic variance of a quasimaximum likelihood estimate for a non-Gaussian process contains certain integrals of the fourth order cumulant spectral density. If we apply the asymptotic theory we are required to estimate these integrals. Here we shall propose some operational consistent estimates for them.
