... This is clearly inappropriate for items such as milk and alcohol, where it is clearly seen that persons who tend to consume the items more often also tend to consume more of it when they do consume it. On the other hand, the NCI approach does not easily lend itself to implementation in nationwide food consumption surveys such as the National Health and Nutrition Examination Survey, because incorporating survey weights into the analysis requires additional programming and is quite intensive from a computational viewpoint.

... If p denoted the overall prevalence, then n1 3 p1 1 n2 3 p2 p5 n1 1 n2 The percentiles of the usual intake distribution of the nutrient in the aggregated group are estimated as usual, using the daily intakes reported by persons in both subgroups together. Approach 2 When the numbers n1 and n2 of persons in each of the two DRI groups was small, the committee could not obtain a reliable estimate of the two prevalences, p1 and p2.
