Body energy/body weight (ENGY), percent water (WAT%) and proportional weight of the epididymal fat pad (FPAD%) were used as independent variables to predict fat percent (FAT%) in three independent studies with mice. Prediction equations were found to be valid based on the following criteria: 1) high correlations between observed FAT% and predicted fat percent based on prediction equations derived from an independent data set and 2) negligible correlations between predicted fat and FAT% minus predicted fat. Although any two of the independent variable generally provided a better fit than one variable, use of one of the three independent variables is probably sufficient for most applications. Based on the coefficient of determination, ENGY was the best single predictor of FAT% followed by WAT% and FPAD%. However, FPAD% may be most useful in large experiments where a rapid procedure is essential.
在三项独立的小鼠研究中，身体能量/体重（ENGY）、水分百分比（WAT%）和附睾脂肪垫的比例重量（FPAD%）被用作自变量来预测脂肪百分比（FAT%）。基于以下标准发现预测方程是有效的：1）根据从独立数据集得出的预测方程，观察到的FAT%与预测脂肪百分比之间具有高度相关性；2）预测脂肪与FAT%减去预测脂肪之间的相关性可忽略不计。尽管任何两个自变量通常比一个自变量能提供更好的拟合，但对于大多数应用来说，使用三个自变量中的一个可能就足够了。基于决定系数，ENGY是FAT%的最佳单一预测指标，其次是WAT%和FPAD%。然而，在大型实验中，当快速程序至关重要时，FPAD%可能最有用。
