Essen.
Most recently Wayne has changed how the file_struct and its

Goodness-of-fit for zero-truncated poisson distribution
...instance:
Fi <- c(8, 5, 0, 4, 0, 1, 2, 0, 0, 1)
muHat <- trunpoismle(mean(Fi))
class <- 1 : 10
Exp <- muHat^class * exp(-muHat) / factorial(class)
Exp <- Exp[-1] / (1- Exp[1]) * sum(Fi)
# individuals seen 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 times
# This distribution maybe reduced to:
FiPooled <- c(8, 5, 4, 4)
# individuals seen 1, 2, 3-4 and > 4 times to apply chi-square tests
I would like to collapse the expected values the same way. Does anyone
have some tips or point out on a function I could have missed to pool
classes of a contingency table (or even to perfom the GOF test it...
