Roche-Wainer-Thissen(RWT)预测模型开发于1975年，根据年龄、当前身高、当前体重、当前骨龄和父母的平均身高预测儿童的成年身高。总体而言，该方法运行良好；但是，该过程中有某些步骤可以改进。对当前版本的RWT预测模型的七种变体进行了研究，并从预测的准确性和可靠性方面进行了比较，最终提出了一种对美国白人成年人身高的预测建议。推荐的方法称为多变量三次样条法[MCS2(1)]，在RWT预测模型的平滑部分使用三次样条法，与当前的多变量半度量平滑(MS2)方法相比，方法更简单(即步骤更少)，预测和实际成人状态之间的最大偏差更小。(C)1993年Wiley-Liss公司
The Roche-Wainer-Thissen (RWT) prediction model, developed in 1975, predicts the adult stature of a child based on age, current stature, current weight, current skeletal age, and the average stature of the parents. Generally, the method has worked well; however, there are certain steps in the procedure that can be improved. Seven variations of the current version of the RWT prediction model are investigated and compared in terms of the accuracy and reliability of prediction, culminating in a recommendation for the prediction of adult stature in Caucasian Americans. The recommended method, called multivariate cubic spline smoothing [MCS2(1)], uses cubic splines in the smoothing part of the RWT prediction model, resulting in a simpler (i.e., fewer steps) method with smaller maximum deviations between predicted and actual adult statures than the current multivariate semi-metric smoothing (MS2) method.
