To add the duplicate observations, we sort the data by id, then duplicate the first five observations (id = 1 to 5). This leads to 195 unique and 5 duplicated observations in the dataset. Thus unique observations are tagged with value 0, and all duplicate observations are tagged with values greater than 0. For checking double data entry, in which you expect just one surplus copy for each individual record, you can generate a tag variable and then look at observations with tag not equal to 1 because both unique observations Count unique values in Stata. codebook is a great command in Stata.
