Conceptually, this would require Stata to have a list of values that
you want to display. In -tab- Stata obtains that list from the values
that actually occur in the data. This is a sensible default, but if a
value that you want to see occurs zero times in the data, than it will
not be displayed. Ben Jann's -fre- can obtain this list of values from
either the value labels you have attached to your variable or you can
specify all the values you want to see. To install -fre-, type in
Stata:
ssc install fre
followed by -help fre- to read more on how to exactly use this command.
Hope this helps,
