Numerical example of screening for breast cancer
Let’s work with some numbers in connection with extensive and
intensive margin using the screening example mentioned in the book.
Let’s assume that p, probability of detecting true cases,
is 0.9; q, probability of a false positive, is 0.05;
f, probability of true positives in the population, is
0.2.
Consider the initial population of 1,000, what is the yield
(total number of detection)?
Now, suppose that we extend the screening to a new...
