st: question on distribution of values
Dear Statalist Users,
Here's an example of the data I'm working with:
Order# Qt Zip
1 5 00011
1 5 00012
1 5 00013
1 5 00014
2 3 00021
2 3 00023
3 8 00031
3 8 00035
3 8 00036
Here are my problems:
1. The quantity of packages (qt) listed does not correspond directly to the zip code. For example, Order #1 requested 5 packages, to be distributed among each of four zip codes, or 1.25 packages per unique zip, not 5 packages per zip code.
2. I have yet to find the correct syntax that would allow me to create a variable that would show the distribution of Qt among the zip codes. I've played with egen, but can't get it to work.
So my question is:
how can I take one value of Qt (or if needed, an average of Qt), within each unique Order# and divide it by the number of unique zip codes by order#? Also, if it helps, the order number is listed each
time the zip code changes, so a count of order# would probably work, too, but I'd prefer to do it by Zip.
