MPE = mean percentage error, LOA = limits of agreement, RMSPE = root mean square percentage error, SD = standard deviation, p10 = proportion of weight estimates within 10% of actual weight, p20 = proportion of weight estimates within 20% of actual weight. A negative MPE is indicative of a bias to underestimation of weight.
