Consumptions uncertainty
In MCRA, in an acute exposure assessments, individual consumption day data are resampled, thus preserving the multivariate consumption patterns and associated weights and/or other individual characteristics. In MCRA we resample the set of individuals x number of survey days. We think that this implementation better reflects the notion of acute exposure which is expressed as the normalized intake per day. For chronic exposure assessments the resampling algorithm remained unchanged and the set of individuals (with corresponding days) is resampled.
