Individual Events Become Binned Data---I

• If we have so many events that I can divide them into K groups of () events where p has the same value for each member of the group, then:

  

  where

  

  and we return exactly to formulae in Section 3.3.

• Further, if is large for each k, our Poisson distributions become Gaussian and we can use method to analyze data.

  This is the only case where is correct in the sense of giving the best answer.
