ASYMPTOTICS OF SPECTRAL DENSITY ESTIMATES

Econometric Theory, 2009
We consider nonparametric estimation of spectral densities of stationary processes, a fundamental problem in spectral analysis of time series. Under natural and easily verifiable conditions, we obtain consistency and asymptotic normality of spectral density estimates.

Spectral Densities

1990
Abstract The previous two chapters were devoted entirely to the concept of multiple scattering, the concept of structure constants, and approximations dealing with the problem of disorder. Since the same formal language was used for both ordered and disordered systems, it is now comparatively easy to discuss spectral densities quite ...

Spectral Density Estimates

1985
The periodogram was introduced in Chapter III. Here we shall consider it in greater detail. It was originally introduced by Schuster [1898] as a tool to detect hidden periodicities. Suppose that $${Y_kappa} = {X_kappa} + {m_kappa}$$ where X κ is a weakly stationary process with mean zero and a continuous spectral density f (with f(π) = f(− π ...

Rational Spectral Densities

2002
Purpose Processes with rational Power Spectrum Density (PSD) play a very important role for modelling second order properties of processes. In particular, piecewise continuous PSDs can be approximated with an arbitrary precision by rational PSDs (and even polynomial PSDs, see Appendix F).

Spectral Density Matrix Transformations

Journal of the IEST, 2017
Abstract Reference criteria for a multiple degree-of-freedom (MDOF) random vibration test is generally provided in terms of an acceleration-based spectral density matrix (SDM). This SDM may be developed in terms of the auto-spectral densities (ASDs) and cross-spectral densities (CSDs) computed from the time histories acquired from an ...

Description II: Spectral Density

1971
The probability functions which we have considered give an account of the part played in a random process by values of x of different magnitudes, but they do not reveal the course of the variation of x with time except through the auto-correlation function R(τ) as a function of time interval τ.
