Time Series Forecast with Singular Spectrum Analysis

We propose a novel approach for constructing Singular Spectrum Analysis (SSA) forecast based on estimating new coefficients of Linear Recurrent Formula. The results indicate that the proposed method is more reliable in comparison to the widely used approaches that were proposed along with SSA. We conduct simulation studies to compare the relative performance of the new method with the existing ...

Generalized Singular Spectrum Time Series Analysis

This paper is a study of continuous time Singular Spectrum Analysis (SSA). We show that the principal eigenfunctions are solutions to a set of linear ODEs with constant coefficients. We also introduce a natural generalization of SSA, constructed using local (Lie-) transformation groups. The time translations used in standard SSA is a special case. The eigenfunctions then satisfy a simple type o...

Spectrum analysis of cardiovascular time series.

The demand for noninvasive assessment of cardiovascular control parameters has promoted the use of spectrum analysis. These techniques have been applied on a broad basis; however, because of the abstract mathematical approach, spectrum analysis in physiology is still not fully accepted by some circles in the scientific community. Thus it is the goal of the following review to focus on the ratio...

Agilent PSA Performance Spectrum Analyzer Series

Its wide dynamic range makes the spectrum analyzer the test instrument of choice for measuring harmonic distortion, intermodulation distortion, adjacent channel power ratio, spurious-free dynamic range, gain compression, etc. Distortion measurements such as these are bounded on one side by the noise floor of the spectrum analyzer and on the other side by the signal power strength at which the s...

Singular Spectrum Analysis for Time Series

Singular spectrum analysis (SSA) is a technique of time series analysis and forecasting. It combines elements of classical time series analysis, multivariate statistics, multivariate geometry, dynamical systems and signal processing. SSA aims at decomposing the original series into a sum of a small number of interpretable components such as a slowly varying trend, oscillatory components and a ‘...
