Mathematical models have been fitted to the widely used standards of birth weight by gestational age that were published by Thomson, Billewicz and Hytten (1968). The models give a close fit to the data and allow an individual infant's weight to be scored on a continuous scale as a number of standard deviations from the expected weight.
数学模型已被应用于汤姆森、比莱维茨和海顿(1968年)发表的广泛使用的按孕周划分的出生体重标准。这些模型与数据拟合度很高,并允许根据个体婴儿的体重相对于预期体重的标准差数量在连续尺度上进行评分。
