Betreff: st: generating count and sum variable over two different
categorical variables
Dear listers,
I´m doing a survival analysis, but also need to present some graphs on a
regional level. In other words my data is setup on an individual level with
categorical variables for year and region. What I need to do is generate a
count variable for the cases counted over year AND region. Using the - egen
total- command I´m only able to sum over either year or region. Not both as
far as I understand. Also is there a way to sum over two categories, not
just one.
ie my data is setup according to
case year region
and i´d like it setup acording to
case year region #cases/year/region
Regards,
M
