Noisy time series. Noisy time series data (symbols) and results of the numerical integration of the estimated model (solid lines; cf. Eq. (3)). In spite of slight numerical discrepancies between the estimated parameters and their target values (see Additional file 1), the estimated model accurately predicts the dynamics of the target system, indicating quasi-redundancy [e.g., [27] and [25] ] or "sloppiness" [26] among the parameters.
