Speaking Stata: On structure and shape: the case of multiple responses
Abstract. A frequent problem in data management is that datasets may not arrive in the
best structure for many analyses, so that it may be necessary to restructure
the data in some way. The particular case of multiple response data is
discussed at length, with special attention to different possible structures;
the generation of new variables holding the data in different form; valuable
inbuilt string and egen functions; using foreach and
forvalues to loop over lists; and the use of the reshape command.
Tabulations and graphics for such data are also reviewed briefly.
