Dear all,
I would like to do a goodness-of-fit test on my data to see if they follow a
mixture of 2 poisson distributions. I have small numbers for observed values.
Most of them <5. The chisq.test gives warning message: Chi-squared
approximation may be incorrect in: chisq.test(x , p = prob). However, the
option sim=TURE would suppress the warning message. Does that mean with the
option sim=TURE, the result from chisq.test is valid, even though most of the
cell counts <5?
Thank you very much!
Sincerely,
Jian
