Analysis of almost-periodic and almost-proportional characteristics of a representative sample local minima time series

Abstract

Abstract The methods’ problem for analyzing nonlinear oscillations is now a general scientific and fundamental one, especially in the information systems field with a data large amount. In this paper, the analysis is carried out on an exchange data test example to identify hidden connections, general patterns, trends and fluctuations. Based on the analysis results, it is expected to reveal the desired ergodic dependence, as well as the data behaviour distinctive features in the almost-periods and near-proportions identified areas.
