WebSpectral analysis. This macro provides the following tools for spectral analysis: the periodogram, the cumulative periodogram, the estimated spectral function, and spectral model checking. These functions are very valuable for stationary processes and provide frequency analysis methods for residual and ARIMA model diagnostics. WebSingular Spectrum Analysis ( SSA ) is a relatively new technique ( although Lorenz suggested something similar 1956 ) that is starting to be more widely used. The jury is still out on just how much underlying structure, if any, there actually is in financial time series. shaolin film complet
