Subject   st: -tabulate- looped over levels with -foreach-: how to count each subject only once, and display row percentages?
Date   Sat, 1 Feb 2014 12:12:52 -0800

I've written this command to produce a table, in which I seek to display variables <Age> and <Gender> in columns, over levels <Group> in rows:

qui levelsof Group, local(levels)
foreach l of local levels {
    tabulate Gender Age if Group == `l', row
}

Two questions about which I'd like to ask advice:
1. In my dataset there are multiple observations per Subject. How can I count each Subject only once?
2. Although one can use the -row- option with -tabulate-, in this case within -foreach- looping, the program returns "option row not allowed."

Any advice would be appreciated.


Best wishes,
Michael McCulloch
