The RWT method for predicting adult stature from childhood variables uses the current recumbent length and weight of the child, the stature of each parent, and the skeletal age of the child as predictor variables. There is only a small increase in the errors of prediction if population mean values are substituted in the prediction equations when the father's stature, the skeletal age of the child, or both these variables are unknown. This modified method is more generally applicable than the original RWT method.
利用儿童期变量预测成人身高的RWT方法，将儿童当前的卧位身长和体重、每位父母的身高以及儿童的骨骼年龄作为预测变量。当父亲的身高、儿童的骨骼年龄或这两个变量均未知时，如果在预测方程中代入总体均值，预测误差只会有小幅增加。这种改进方法比原始的RWT方法更具普遍适用性。
