A Semiparametric Transformation Approach to Estimating Usual Daily Intake Distributions
估计通常每日摄入量分布的半参数变换方法
The distribution of usual intakes of dietary components is important to individuals formulating food policy and to persons designing nutrition education programs. The usual intake of a dietary component for a person is the long-run average of daily intakes of that component for that person. Because it is impossible to directly observe usual intake for an individual, it is necessary to develop an estimator of the distribution of usual intakes based on a sample of individuals…
