On the Objective Functions page the properties for calculation of comparison statistics are specified. The basic statistics used by AutoCal are the Output measures that include a single comparison statistic between an observed and a simulated time series. These basic measures can then be aggregated into different Objective functions, for instance according to spatial location, type of variable, or type of statistic. Finally, the defined objective functions are aggregated into a single statistic that is used by the optimisation algorithm.
