Since there is an almost infinite number of ways in which a process may exhibit non-stationarity, a specific class of non-stationary processes is selected and studied. This includes first order autoregressive, AR(l), series with a time varying coefficient. Its spectral representation is obtained through the autocorrelation matrix according to the Karhunen-Loeve theory and the evolutionary properties of the process are studied through the eigenfunctions and eigenvectors of the autocorrelation matrix.

Abstract

Since there is an almost infinite number of ways in which a process may exhibit non-stationarity, a specific class of non-stationary processes is selected and studied. This includes first order autoregressive, AR(l), series with a time varying coefficient. Its spectral representation is obtained through the autocorrelation matrix according to the Karhunen-Loeve theory and the evolutionary properties of the process are studied through the eigenfunctions and eigenvectors of the autocorrelation matrix.
