[R] How to test a time series fit the Poisson or other process?

[Spencer Graves]

	  I just did  RSiteSearch("poisson time series").  The second and third
of 75 hits seemed relevant to your question.  (e.g.,
http://finzi.psych.upenn.edu/R/Rhelp02a/archive/58054.html)  Some of the
other responses did not seem relevant, but I didn't look at all of them.
 This response menitoned Jim Lindsey, whose "R code" web site is
"http://popgen0146uns50.unimaas.nl/~jlindsey/rcode.html".

	  Hope this helps.  If I had a long time series of Poisson counts, I'd
be tempted to try a standard time series model on the square root of the
counts.  If the results were dramatically different from what I got from
some more sophisticated modeling strategy, I'd look very carefully at
both to make sure I hadn't made a mistake some place.  If it were not
that important, I might just apply standard time series techniques to
the square roots of the counts and go on to the next task.

	  hope this helps.

p.s.  If you'd like more information from this listserve, PLEASE do read
the posting guide! "www.R-project.org/posting-guide.html".  I believe
that people who follow that guide generally get quicker, more useful
replies.  This is especially true for those who supply a simple, toy
example in a few lines of R code that someone else can copy from an
email into R, test a few ideas, and craft a reply in a very few minutes.
