# Spectral analysis of a stationary stochastic process

From Encyclopedia of Mathematics

*spectral analysis of a time series*

The same as spectral decomposition of a stationary stochastic process (cf. Spectral decomposition of a random function).

A set of statistical methods that enables one to estimate the value of the spectral density of a stationary stochastic process from the observed data of one (or several) realization(s) of this process (see [1]–[5]). See also Statistical problems in the theory of stochastic processes; Periodogram; Spectral density, estimator of the; Maximum-entropy spectral estimator; Spectral estimator, parametric.
