Estimation of the Usual Daily Intake Distributions of Ratios of Dietary Components. Dietary Assessment Research Series Report 5
扩展了Beale(1962)的方法，先估计个体每日膳食成分比值，再应用爱荷华州立大学的方法估计该比值的日常摄入量分布，对营养学研究者评估膳食质量有参考价值。
Rations of usual intakes of dietary components, such as the percent of calories from fat, are important indicators of dietary adequacy. The authors of this paper discuss the problem of estimating the intake distribution of ratios of dietary components by using an extension of the method developed by Beale (1962). They first estimate the daily ratio of dietary components for each individual to obtain a nearly unbiased ratios estimate and then apply the method developed at Iowa State University to estimate the distribution of usual intakes of the ratio.
