Subject: Infant Mortality (IM) Pi Factor
Reference RAC Journal, Third Quarter-1999 Page 4 Pi_IM Equation:
(1) When SS=0.5; Pi_IM(Instantaneous at 5 Year) = 0.7662 and Pi_IM (Average over 5 Years) = 0.4728.
(2) When SS=0.9; Pi_IM(Instantaneous at 5 Year) = 1.3792 and Pi_IM (Average over 5 Years) = 0.8512.
Why does Pi_IM Factor increase when Screening Strength (SS)was increased. High Screening Strength is supposed to give lower failure rate.
