st: RE: CUSUM charts
You don't show your precise data structure but I
guess is that no special .ado is needed for what
you want to do. At worst, you need to
use -sum()-, possibly in conjunction with -bysort-,
to create the cumulative sums after which your graph will be
one of the existing standards.
