Hi Ian
Thanks for the reply. I understand the difference in mean and variance for different distributions.
I understand that this sort of question might not be asked in the SP level exams. But the technicalities would be important when choosing different distributions in the modeling process so was trying to understand the dependence part.
Also, could you please clarify the part related to how would we define number of trials/failure when modeling frequency using Negative Binomial distribution?
