Is there a maximum number of counts one should not exceed when using the negative binomial model? Even if there is a adjustment for exposure (e.g., rate of homicides in a city). I have a data set with over 200 homicides in some cities and I saw a reference in an article of American Journal of Sociology to Maddala's 1977 econometrics textbook that said you should exceed 50 counts. Is this true?
