So you want to tabulate admissions that include a "failure to appear"
(possibly with other charges) by the release codes from the previous admission.
I'm not going to try code yet, but it wouldn't be hard to summarize
to a single record per admission, with
and whether the admission includes a "failure to appear" charge
It would be nice to have a "LEAD" function (analogous to "LAG") to
attach to each admission, whether the *following* admission includes
a "failure to appear" charge, but it'll probably take a little
juggling. Maybe it can be done with LEAD in CREATE -- anybody help with that?
Then, you need to identify the releases that are NOT followed by a
"failure to appear". I don't know how you do that. I suppose, if at
the inmate's next admission there's no "failure to appear", then that
settles it. What if there's no subsequent admission?
Anyhow, there are some moderately tricky data-manipulation issues
here; but the conceptual issue, how you determine whether an inmate
failed to appear after a release, needs to be resolved first.
