Abstract

findunique displays combinations of unique identifiers in a dataset. This command allows the user to find a rule according to which each single observation in a dataset is uniquely identifiable. findunique displays all the possible sets of variables among those specified in varlist whose combined values uniquely identify observations and shows them in order from the most parsimonious to the set with the largest number of variables.
