Force of mortalitylast-survivor Force of mortality for T xy The force of mortality for T xy is de ned as x+t:y+t = f T xy (t) 1 F T xy (t) = f WebUsing the approximate method, we estimate the average number at risk over the period by adding the number at risk at the start and end of the period, and dividing by two. In this case we have 8 present at the start, 5 at the end, so the average number present is 6.5. The crude mortality rate is then given by 3/ (6.5×12) = 0.038 per pig week.
