queueing problems
...some response time data I want to 'correlate' with other data. I
believe queueing is involved so I need to prove somehow (F test?) that
response ~ exponential(...)
How do I go about this? I cant find exponential in 'nlm' or other
functions.
thanks,

tapply, sorting and the heap
...ew and green and I was hoping for a tiny bit of your expertise.
I'm running out of virtual memory (heap?) when summing using tapply. I've
already used --vsize=90M on my hpux machine. (details below)
Can I pre-sort or something to prevent my error?
thanks,
