Title
  • CF3: Stata module to compare two datasets
Author
  • Thomas Steichen
Physical Description
  • code
Notes
  • cf3 matches observations by a record id variable and lists the observations where differences exist. It compares variables of the dataset in memory (the 'master' data) to the corresponding variables in a file (the 'using' data). Only the variable values are compared. cf3 differs from cf in that: 1) the id() option, which names the common record id variable in each file, is required; 2) verbose is presumed but option noverbose will suppress some output; and 3) it will not stop if there is a differing number of observations in the two files. Generally, the id variable values should be unique within each file. If the id values are not unique then proper matching may not occur; cf3 will warn the user but will continue. Incorrectly-matched observations, where the variables being compared also differ, and unmatched observations will be reported as differences.
