Handle: RePEc:boc:bocode:s412801 Note: This module may be installed from within Stata by typing "ssc install expandby". This video demonstrates how to identify and remove duplicate observations.

In Stata, several programs are available to detect the duplicates and can also optionally drop the duplicates. One of the programs is called dups . The program dups is not a built-in program in Stata, but can be installed over the internet using search dups (see How can I use the search command to search for programs and get additional help? for more information about using search) . Option for duplicates tag generate(newvar) is required and speciﬁes the name of a new variable that will tag duplicates. Option for duplicates drop force speciﬁes that observations duplicated with respect to a named varlist be dropped. The force option is required when such a varlist is given as a reminder that information may be lost by For group id=1, keep observation 2.
