The model <strong>was assumed<\/strong> to demonstrate satisfactory data approximation if the sets of deviations of the model and empirical data for both time series satisfied a number of statistical criteria (for the selected significance level). The frequency distributions of deviations between the theoretical (model) trajectories and empirical datasets <strong>were tested<\/strong> for symmetry (with respect to the Y-axis; the Kolmogorov\u2013Smirnov and Lehmann\u2013Rosenblatt tests) and the presence or absence of serial correlation (the Swed\u2013Eisenhart and \u201cjumps up\u2013jumps down\u201d tests).
