Nonlinear prediction of CNST_e signal. The blue curve is the observed signal, the red is predicted and the green curve is the normalised error which is less that one and so marginally better than a linear prediction model given by (7). The prediction lags behind the observed signal by 1Â day so is not ideal for practical predictive purposes but is a good test of the data model
