The corresponding observed proportion of cases PCF* found among the fraction q of the AARP population at highest risk and the proportions p_R and p_CC of cases found among the fractions and of the AARP population at highest risk are also shown. and are based means over five test sets of the model after recalibration using 5-fold cross-validation.
