I. Аннотация: In this paper the amplitude modulated version of random prosess is investigated. There is considered the case when irregularities in observations are defined as arbitrary sequence of independent random values. In this case the estimations of mathematical expectation, covariance function and spectral density have been constructed. The statistical properties of the esimations have been studied. 2007-01-01T00:00:00Z https://elib.bsu.by:443/handle/123456789/93513 Заглавие документа: Limiting Distribution of the Variogram Estimator Авторы: Tsekhavaya, T. V.; Troush, N. N. Аннотация: The paper deals with the problem of a statistical analysis of time series connected with the estimation of variogram. We present the limiting expressions of the first two moments and the higher order cumulants of the classical variogram estimator of Gaussian intrinsically stationary stochastic process with continuous time. These expressions are then used to prove the theorem concerning the asymptotic distribution of the variogram estimator. 2007-01-01T00:00:00Z https://elib.bsu.by:443/handle/123456789/93512 Заглавие документа: Some Properties of Absolute Order p of α-Stable Random Variables Авторы: Troush, N.
