The Definition of incidence rate is defined as : new event/person-time
Now there's my data：
Mutation Without mutation incidence rate 0.01345908 0.00407633
Where 0.01345908 = (N.O new event with mutation case) / (person year of all case from mutation + person year of all case from without mutation)
Where 0.00407633 = (N.O new event without mutation case) / (person year of all case from mutation + person year of all case from without mutation)
It's trivial that this two sample is not independent (probability,that's, incidence rate would influence by each case due to person year on Denominator)
So, i can't undergo two-sample proportion test. (due to dependent)
Well , i want to know how to test whether this two incidence rate reach statistic significant , how can i do in this situation ? is anyone can help me ?
Thank a lot.
