Chapter 2: effect of base-rate on posterior predictive result
For example, if the contingency table data had instead been:
URNall=100;
HIT=45; MISS=5; CR=47; FA=3;
URNhm=HIT+MISS;
URNcf=CR+FA;
it would change the disease base rate from p(D|i)=0.005 to p(D|i)=0.5, and the posterior probabilities to p(D|+,i)=0.9375 and p(D|-,i)=0.0962.
