I have two populations of earthquakes that happened in the same area, the Mediterranean Sea, but in different time periods. The first gives me a rate of 27 per day, and the second 40. How can I test whether this difference is significant?

do you have the daily # of occurances over a period of time (say a decade)? – DankMasterDan Oct 01 '15 at 22:52

Yes. The first population is the general one; twelve years of observations. – aimilios Oct 01 '15 at 22:54

I believe the question you are asking is how to check whether observations of 2 different Poisson processes have different means. Several possibilities are given here:

1Can you expand on this? Otherwise, it should probably be a comment. – gung - Reinstate Monica Oct 01 '15 at 23:43
