Hi All (first timer here again)
I've sent this message once before but I'd like to add a bit more.
I'm trying to conduct power and sample size to detect a change over years from poisson data
Is there some simulation routine in R that I could use (or that someone has used eslwhere) on a set of generated data that has a mean, say 10% less than current estimates?
glm.Male_glm(M~year*strata,family=poisson,offset=duration) levels(year) [1] "2000" "2001"
levels(strata)
[1] "0-4" "4.1-8" "12.1-16" "8.1-12" Norm Good Fisheries Biologist (Mathematician) Southern Fisheries Centre PO Box 76, Deception Bay Q 4508 telephone 3817 9588, fascimile 3817 9555 ********************************DISCLAIMER**************************** The information contained in the above e-mail message or messages (which includes any attachments) is confidential and may be legally privileged.
