33 died overa 10-year period from COPD, whereas only 24 such deaths could be expected based onstatewide mortality rates.
I came up with ppois(q = 33, lambda = 24, lower.tail = FALSE), but it seems it is ppois(q = 32, lambda = 24, lower.tail = FALSE). I am confused with the q value. Why is it 32 instead 33? thx much ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
