st: Data management

Dear Statalist users,

I am analyzing administrative database. There are multiple billing
submitted for one event. I would like to create one record for each
event. Please suggest how to collapse multiple billing records into
one record per event for an individual.

Example

ID            billid       Amt($)                  bill from
    bill thru                 proc1     proc2     proc3     proc4
billtype

1              x1           345                         20050128
      20050131             123         345
            interim

1              x2           1000                       20050201
     20050203             993         452         462
       interim

1              x3           2000                       20050204
     20050206             991
               interim

1              x4           150                         20050207
      20050210             414         416
            Final

Apparently the billing is for services rendered between 20050128 thru
20050210. Multiple bills/claims were submitted for one episode. I will
highly appreciate suggestion for collapsing information from interim
bills into the final one to create one record for an episode without
loosing information from interim bill/claim.

Thanks.
