Multiple Decrement Models
Hello all! I'm in need of some notation assistance. The notation for the probability of death from 60 to 62 due to any decrement is given as 2q(τ)60. And I've been thinking that q(τ)60 + p(τ)60*q(τ)61 was an analagous formula able to use. However, when I was working through a few life table questions this was given as: # failures due to any decrement between 60 and 62/ I(τ)60. Which should yield the same answer right? But for some reason thats not the case.
Also given: x l(τ)x d(1)x d(2)x d(3)x 60 1,000 35 65 40 61 l(τ)61 40 d(2)61 35 62 712 51 80 581 where l(τ)61 = 860 and d(2)61 = 73 Last edited by isaiahbarrett27; 08042019 at 11:08 AM..
