世界卫生组织（卫生组织）与世界各地的一些研究机构合作，正在制定新的儿童生长标准。作为选择最佳统计方法的广泛协商进程的一部分，世卫组织召集了一组统计学家和儿童生长专家，以审查现有方法，制定评估其优缺点的战略，并讨论在构建新的生长曲线过程中可能面临的方法问题。为了选择要使用的方法，该小组提出了一个两阶段的决策过程。首先，根据一系列既定的标准选择一些相关的方法，其次，使用现有的测试或其他既定的程序对方法进行比较。该小组回顾了30种获得生长曲线的方法。使用预先定义的标准，结合五种分布和两种平滑技术选择一些。由于所选方法的数量太大，无法进行充分检验，因此建议进行初步研究以评估五个分布的拟合优度。基于分布的性能较差的方法将被淘汰，剩余的方法将被充分测试和比较。版权所有(c) 2005 John Wiley & Sons, Ltd。
The World Health Organization (WHO), in collaboration with a number of research institutions worldwide, is developing new child growth standards. As part of a broad consultative process for selecting the best statistical methods, WHO convened a group of statisticians and child growth experts to review available methods, develop a strategy for assessing their strengths and weaknesses, and discuss methodological issues likely to be faced in the process of constructing the new growth curves. To select the method(s) to be used, the group proposed a two-stage decision-making process. First, to select a few relevant methods based on a list of set criteria and, second, to compare the methods using available tests or other established procedures. The group reviewed 30 methods for attained growth curves. Using the pre-defined criteria, a few were selected combining five distributions and two smoothing techniques. Because the number of selected methods was considered too large to be fully tested, a preliminary study was recommended to evaluate goodness of fit of the five distributions. Methods based on distributions with poor performance will be eliminated and the remaining methods fully tested and compared. Copyright (c) 2005 John Wiley & Sons, Ltd.
