The Roche- Wainer- Thissen (RWT) method estimates the adult stature of an individual from data recorded at a single childhood examination. The data required are recumbent length, nude weight, midparent stature, and hand-wrist skeletal age. If necessary, a measurement of the child's stature can be transformed to be approximately equivalent to recumbent length with little loss of accuracy. When applied to data from three longitudinal growth studies, the prediction errors with the RWT method were smaller than those with the method of Bayley and Pinneau.
Roche et al. (Mon,) studied this question.
