Abstract

fagan creates a plot showing the relationship between the prior probability specified by user over the range 0-1, the likelihood ratio (combination of sensitivity and specificity), and posterior test probability. fagan plots an axis on the left with the prior log-odds, an axis in the middle representing the log likelihood ratio and an axis on the right representing the posterior log-odds. Lines are then drawn from the prior probability on the left through the likelihood ratios in the center and extended to the posterior probabilities on the right.
