“…The reason for this is that the exposure estimates contain both the variation between and within individuals, whereas for a long-term exposure only the variation between individuals is relevant, since dayto-day variations level out in the long run. To remove the within individual variation from the exposure distribution variance component models have been developed, including the Iowa State University Foods Model (ISUF) (Nusser et al, 1996(Nusser et al, , 1997, the Betabinomial-Normal model (BBN) (de Boer et al, 2009), the LogisticNormal-Normal model (LLN, NCI) (Dodd, 2011;, the Statistical Program to Assess Dietary Exposure (SPADE) (van Rossum et al, 2011) and the Multiple Source Method (MSM) (Harttig et al, 2011). For an overview of these models, we refer to .…”
