Remarks

Data are considered as supplemental with respect to the current dataset if they contain information about the same variables, but observed at different individuals.

The data in a categorical dataset can be represented in disjunctive form by means of a matrix having as many rows as the number of individuals in the dataset, while its number of columns is equal to the sum of the categories in each dataset variable. For a given row-column pair, the matrix has entry equal to 1 if the category corresponding to the given column has been observed at the individual corresponding to the given row, otherwise the entry is zero.
