A singular spectrum analysis: problems and solutions

The paper has examined various aspects of the singular spectrum analysis (SSA) method.The original purpose of the method is to optimize harmonic (spectral) analysis of time series.A theoretical justification based on integral equations was given for the SSA.A solution to the problem of large dimensionality of the autocovariance matrix (AM) was prop
