lname() specifies the name to be given to the value label created to hold the labels; lname() implies label. The the unique values of the variable in question, even though such distinct values could all be repeated in the data—and, in particular, 2, 3, and 4 are indeed repeated. One logic behind that terminology is that if you remove all the duplicates from these data, then you are left with four distinct values, each of which occurs once. The dups id, unique key(id) group by: id groups formed: 1 groups of duplicate observations: _group _count id 1 3 18 unique observations: _group _count id 1 1 191 2 1 171 3 1 147 4 1 26 5 1 22 An option called terse can be added to get summary information on duplicates. You can do the above by using by:, which is one of the most versatile features of Stata.

100 unique IDs, but for each ID it gets repeated multiple times (as shown above) and I want to figure out how many of my unique IDs satisfy some criterion (e.g. test score>500), then your input there should tell me that? If you want to count distinct IDs, as I guess you do, count() is irrelevant, as it counts non-missing values regardless of how many distinct values that means. Here is a demonstration.

STATA – SPSS-AKUTEN

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.

It is always a good idea to browse and describe the dataset before you delve into it.. To obtain summary statistics of all the variables in the dataset, simply type summarize. 1.2 STATA Basics STATA is available in a variety of platforms and flavors.
