1. The problem statement, all variables and given/known data How accurate is the estimate for (cohort) generation time (the type you'd have on a life table)? 2. Relevant equations Cohort generation time: Tc = Sum of (x*Fx)/sum of Fx 3. The attempt at a solution Tc = 2.77 (for 7 generations) So the generation starts of with 100 organisms and is cut down to 0 after 7 generations. From this, I get an estimate of 2.77, how can I find the amount of accuracy from this?
