New modifications of second- and third-order periodograms
V. G. Alekseev A. M. Obukhov Institute of Atmospheric Physics, Russian Academy of Sciences
Abstract:
New modifications of the second- and third-order periodograms are described which serve as “half-finished products” in constructing statistical estimators for the spectral and bispectral densities, respectively, of a strictly stationary stochastic process $\{X(k), k\in \mathbb Z\}$. A distinguishing feature of both modified periodograms is essentially the smaller value of their variances in comparison to those for previously know modifications.
Keywords:
stationary stochastic process, spectral density, second-order periodogram, bispectral density, third-order periodogram, Jackson's type kernels.
