Hi guys, as u can see, I'm a little behind with CT4 but neways I have a ques. about the exposed to risk defn for calendar rate intervals...
On page 24, it states that P(x+1, 1 Jan next year) is the same as P(x, 31 Dec).
Can anyone explain this because I think that by 1 Jan next year, the number of ppl in the group would have changed because of Dx, etc....
