Poly-Gaussian models in describing the signals of Lorenz dynamic system

Singling out the characteristic areas with typical dynamics in Lorenz system signals by means of non-harmonic spectrographic analysis, a method of representing the distributions of signal probabilities has been developed. Interconnections have been established between the singled out areas of Lorenz system typical dynamics and distribution of probabilities. The minimal number of poly-Gaussian components, necessary for representing the signals with required accuracy, has been assessed.
