Another method for importing data into Stata is to use a data dic-
tionary. This involves two files: (1) the data file and (2) a data diction-
ary file that tells Stata how to interpret and import the data. Often
data files are not just the data, but rather have additional information
about the experiment. This may be several rows of information at the
beginning of a file before the actual data. An example of this is shown
in Figure 2.5.
