This model implements the sensor characteristics described in [1]. It creates a sequence of random values with an interval of 15 minutes, smoothly interpolates the connecting lines between theses values, and superposes the true glucose concentration with the resulting sensor error.
Parameters
- PACF: Partial autocorrelation function coefficient. In the paper, it is fixed to 0.7, but it can be adapted to obtain different noise profiles.
- alpha: Relative error.
- beta: Constant offset.
