Some types of data sets are good only to serve as validation sets, for example, the doubly labeled water data set, where there is only one reading of total energy expenditure every two weeks.
As mentioned earlier, doubly labeled water is the most accurate method to estimate energy expenditure, but provides only one reading per 14 days.
