Thanks Jim. BTW the times in x and y are in ascending order (time of
occurrence).
If I do it this way, how do I actually read the data in and store in
the file? Toy code, please.

Correct.

Could you ex
The way you do it is to compute the cross-intensity function (you can
google this; a key name is David Brillinger). The general problem is
that of system identification for point processes.

I am running an expt that presents a point process input x and
measures a point process output y. The times of each event are
recorded. The lengths of the data records of x and y are necessarily

save these data after each experiment
