Goodness of fit to Poisson / NegBinomial
All,
I have some data on parasites on apple leaves and want to do a
goodness of fit test to a Poisson distribution. This seems to
do it:
mites <- c(rep(0,70),
rep(1,38),
rep(2,17),
rep(3,10),
rep(4,9),
rep(5,3),
rep(6,2),
rep(7,1))
tab <- table(mites)
NSU <- length(mites)
N <-
