Abstract: Assessments of dietary adequacy should rely on estimating usual nutrient intake distributions. Such estimates for a population may be obtained from data collected in dietary surveys. We propose a semiparametric approach to transform the observed intake data, which are not normally distributed, into normality and to remove the dependence between individual intake means and variances.
