摘要:
An estimate for the spectral density of a stationary autoregression–moving average process with a given mean-square accuracy is proposed. In the construction of the estimate, we use the sequential analysis approach, which involves a special choice of the observation termination instant, depending on the estimation accuracy. An asymptotic formula for the average number of observations is obtained.
