net.simplace.util.statistics.SignedBias

Methods for calculating the bias/mean error and comparing signed values. See D. Wallach, Working with Dynamic Crop Models, p. 22 Calculation of bias is the same as for the Bias class. Comparison is different. Bias chooses the set with the smallest absolute value (the closest to 0), whereas SignedBias chooses the set with the smallest signed value (the closest to -Infinity). It can be used to select the maximum of simulated values by setting observed values to 0, having thus the maximal value when UnsignedBias is best.
