![]() Our method provides a maximum likelihood estimation of the power spectral density background according to four different models. The basic philosophy of kSpectra is that only the simultaneous and flexible application of more than one spectral estimation method can provide truly reliable information on a given time series, when the signal-to-noise ratio is low.kSpectra users come from many sciences and industries. We evaluate the power spectral density with the adaptive multitaper method, a nonparametric spectral analysis technique suitable for time series characterized by colored power spectral density. In particular, Periodogram Method (PM), Maximum Entropy Method (MEM) and Multi Taper Method (MTM) are used to invert synthetic SP data generated by cylinder. The toolkit contains procedures for:- estimating the spectrum, cross-spectrum and coherence,- decomposing the time series into trends, oscillatory components, and noise by using sophisticated statistical significance tests, - reconstructing and predicting the contributions of trends and near-periodic components of the time series, - gap-filling technique for analysis of datasets with missing data.kSpectra includes Blackman-Tukey Correlogram, Maximum-Entropy Method, MultiTaper Method, Singular Spectrum Analysis, and Principal Component Analysis. Combination of kSpectra’s spectral methods provides a powerful way to identify and predict oscillatory modes in short and noisy. The toolkit a set of powerful tools for advanced time series analysis in many sciences, ranging from finance and economics to geophysics and biomedical sciences. background spectrum using KSpectra (SpectraWorks, version 2.2). The kSpectra Toolkit from SpectraWorks is a native Mac OS X software for advanced time series analysis. It provides a set of powerful tools for analysis of univariate or multivariate time series arising in various branches of science, ranging from electrical engineering and physics to geophysics, as well as life, biomedical sciences, finance and economics. wavelet analysis, multitaper method (MTM) analysis and singular spectrum analysis (SSA). ![]() KSpectra is a math scientific application for advanced time series analysis on Mac OS X.
