This objective function will produce a match on the overall volume of flow generated but often will produce a poor fit to the timing of flows (Vaze et al., 2011). It has the following form:

Bias Penalty
...
The bias penalty objective function is described in Viney et al. (2009). The equation is given by:
| Equation X |
|---|
where B is the absolute value of the relative bias, as defined in equation (4).

The SDEB statistic is designed to be applied to daily data.
Interpretation
The SDEB ranges from 0 to +∞, where a value of 0 indicates a perfect fit between modelled and observed data.
The coefficient α and the power transform λ are used to balance the three terms within the objective function.
