资源简介：
Concatenation, or joining together, of strings or other values, possibly with extra punctuation such as spaces, is supported in Stata by addition of strings and by the egen function concat(), which concatenates values of variables within observations. In this column, I discuss basic techniques for concatenating values of variables over observations, emphasizing simple loops that can be tuned to suit variants as desired. Commonly, such concatenated strings report a prole or history of each individual within panel or longitudinal data. Such histories can then be analyzed further.
