Statistical Software Components from Boston College Department of Economics

Abstract: strgroup matches similar strings together. This can be useful when merging data that contain typos. For example, "widgets" will not merge with "widgetts" because the strings are not identical. strgroup provides a way to match strings in an objective and automated manner.

Language: Stata
