Hello All --- I am using Intercooled, v.8.2. I was presented w/ an Excel file wherein I need to generate rates of an adverse outcome relative to the number of procedures. Toward that end, I was given the number of surgeries for each clinician and the number of adverse outcomes for each clinician. Computing crude rates was not problematic, however, I now need to stratify by surgical approach & type of machine. My primary problem is that I'm struggling with how to reduce the data from an essentially 'long' form to 'wide' form. An abbreviated example of the data as received is as follows: +------------------------------------------------------------------------------+ | name surger~s technqe total percent wound~er approach | |------------------------------------------------------------------------------| 15. | John Doe 750 100 100 25 . | 16. | John Doe . . . 75 5 divide | 17. | John Doe . . . . . divide | 18. | John Doe . . . . . divide | 19. | John Doe . . . . . divide | |------------------------------------------------------------------------------| 20. | John Doe . . . . . divide | +------------------------------------------------------------------------------+ where 'surger~s' denotes # of procedures for the respective clinician and 'wound~er' denotes the number of adverse events for that clinician. There are about a half-dozen 'approaches' and about a half-dozen machine types (variable not shown) wherein I'd like to compute rates. Note that there are 100 unique clinicians but many of the clinicians occupy multiple lines because they reported 2 or more adverse events. Any suggestions? I've struggled w/ this for a while and haven't had any success using the help file or Stata-list archives...
